The 29 rooms at Monsieur Cadet Hotel & Spa are nicely located in Paris's Theater District near Place de L'Opera, metro lines, and many shops, cafes, and restaurants. The three-pearl hotel is attached to Le Tigre Spa, a Turkish-style hammam with free admission for guests (services cost extra). Built in 1900 and renovated in 2016, the hotel blends the curving lines and minimal furnishings of Bauhaus aesthetics with contemporary features such as flat-screen TVs, minibars, and comfy beds. A full breakfast is offered in-room or in the lounge for an additional fee, though there's no restaurant. There's also a piano bar and terrace that's ideal for people watching. The nearby Hotel 34B - Astotel is kid-friendly and offers free breakfast for guests who book directly with the hotel. 

The Hotel du Continent is a three-pearl, design-centric property in the 1st Arrondissement near the metro and the Tuileries Gardens. Its 25 rooms feature flamboyant, continent-themed decor by designer Christian Lacroix, along with modern amenities like flat-screen TVs and iPod docks. Guests are either exhilarated or exhausted by the dramatic interiors, and some rooms are so petite to border on claustrophobic. A continental breakfast is served, for a fee, and there's an honesty bar, but no full restaurant or fitness facilities. For a less flashy boutique hotel in the same neighborhood, travelers may want to consider the Hotel Costes.

Located near near the Place de la Republique, the boutique-style 39-room Hotel Gabriel Paris Marais, mixes an Art Deco exterior with a Zen-like interior. The monochromatic white, beige, and gray rooms with velvet curtains that help block out noise exude tranquility. They come with free Wi-Fi, flat-screen TVs,  minibars, iPod docks, and sleek bathrooms with tubs or rainfall showerheads. There's also a daily buffet breakfast (included in some rates) that comes with a wide spread of pastries, fruits, and cheeses, many of which are organic. An honor bar in the lounge stocks Champagne, liquors, coffee, and tea. Despite its name, the hotel, which is in the 11th arrondissement, is a good 20-minute-hike to the heart of the Marais. 

This Holiday Inn Express is a mid-range, budget-friendly option occupying an innovative piece of wood-clad architecture overlooking the Canal de la Villette. While the area is set away apart from most main tourist attractions, the neighborhood is vibrant with plenty of bars and restaurants. Simple rooms are spacious (by Paris standards), clean, and well maintained with decent amenities. A decked terrace provides pleasant canal views, and a buffet breakfast -- while not the best quality -- is included. All in all, you get a lot of space for your money though an even more thrifty pick is the St Christopher's Paris Hostel is next door. 

Situated on the fringe of the city center, the 38-room Hotel Europe offers no-frills private rooms at budget prices. While it's out in the 17th Arrondissement, the hotel is only a two-minute walk to the metro and near many eateries. Rooms at the hotel are surprisingly clean and pleasant for a property in this price range, with flat-screen TVs, and extras like desks and wardrobes -- though they lack air-conditioning and Wi-Fi. Single rooms feature en-suite toilets and sinks, but showers are shared. (Other rooms get private, en-suite showers.) There are no common areas other than the lobby that doubles as a breakfast room (breakfast costs an extra fee), and there's no elevator. The nearby Art Hotel Congres offers more features, but it can be almost double the price, depending on the season. 

The Hotel Vice Versa is a 37-room concept hotel whose theme is the seven deadly sins, one per floor, with heaven in the lobby and hell (with steam room) in the basement. The creative, over-the-top decor is by lingerie designer Chantal Thomass. The hotel is fun, playful, and occasionally daring -- body-shaped chairs, skull motif spa floors -- but never takes itself too seriously. It's all tongue in cheek, and guests who can laugh and appreciate quirkiness will have a memorable stay. Those looking for for a design hotel that's a bit less extravagant could try Hotel Du Parc.

The mid-range Residence Champ De Mars enjoys a lovely location near Paris’s most noteworthy attraction: the Eiffel Tower. The atmosphere at the hotel is modern and more like an apartment building than a hotel. The 25 rooms are clean and stylish; they feature flat-screen TVs and coffeemakers. The apartments and studios offer kitchenettes. Unfortunately, all units lack air-conditioning and walls are thin. Perks are limited to free Wi-Fi and an outdoor courtyard, as there is no restaurant, bar, breakfast, or gym on-site. For about the same price, guests can get more amenities at the nearby Eiffel River Gauche which offers breakfast, a free cheese and wine hour, and a computer in the lobby. 

A hidden gem in the middle of the Marais, Hotel Dupond-Smith feels more like a members-only club than an upscale hotel. Dupond-Smith plays off this theme of discretion with an unmarked entrance and eight rooms named after Hollywood aliases and French pseudonyms. Rooms are attractively decorated and thoughtfully curated with luxe amenities like iPads, espresso machines, and scented shower diffusers. Continental breakfast is included in most room rates, but the hotel lacks public amenities like a restaurant, spa, or fitness center. Travelers looking for an equally discreet address with a few more frills might prefer Relais Christine. It’s comparably priced to Dupond-Smith but offers more amenities. 

The Hotel des 3 Poussins is a mid-range hotel located in the 9th arrondissement, a five-minute walk from the Rue des Martyrs and the Grands Magasins of Opera. While slightly outside of the main tourist area, the hotel is close to a plethora of eateries and is a two-minute walk from the Saint-Georges metro stop. Decor is modern, creative, and delightful, with doodle murals and a chalkboard drawing wall. Forty rooms are fairly small, but they’re stylish and feature free Wi-Fi and coffee-and tea-making facilities. There are few on-site features, other than a breakfast buffet and room service for an added cost. The nearby Hotel Lorette Opera - Astotel Paris is a comparable property with design-conscious details but a slightly different aesthetic.

Taking design cues from 1950s pop art, the Hotel George - Astotel is a modern, mid-range property in a lively area of Paris' 9th Arrondissement, between the Palais-Garnier Opera House and Pigalle. Its 46 rooms can be small, although they're stylishly colorful, and efficiently designed. (Some can sleep up to three or four.) All have air-conditioning and include minibars -- with free water, juice, and soft drinks -- flat-screen TVs, and free Wi-Fi. The hotel also offers an open bar and breakfast service in a dining room that includes a children's section. Travelers could also consider the nearby Hotel Helussi, which has Nespresso machines in the rooms, but rates are higher.
