Spread out over nine colorful stories, Citrus Sukhumvit 11 is a simple, mid-range hotel that's popular with Chinese and Middle Eastern tourists (though it also gets a handful of business travelers). The lobby is simple and bright, with rounded furniture and soft decor that consists of circular rugs, plus low ceilings with recessed lighting that give it a contemporary but cozy feel. The hallways are conversely busy, owing to their multihued carpeting with large squiggle designs, though an atrium-style section that runs the length of the building adds some light to each floor. Unlike many Bangkok hotels, this property is entirely non-smoking. 

This property is located just north of the main Sukhumvit area, in a neighborhood full of small shops, restaurants, hotels, and massage parlors (of all sorts). The Nana BTS station is an 11-minute walk from the hotel, or about five minutes away on the hotel's free tuk-tuk shuttle. There are tons of shipping malls within a 10- to 15-minute radius, including Terminal 21(an enormous complex with different floors themed after major international cities) and the upscale Central Embassy, full of designer boutiques. It's reasonably easy to get to major tourist attractions from the hotel: The Grand Palace and Jim Thompson take 15 minutes to reach by car, and Wat Arun is more like 20 minutes away. Suvarnabhumi Airport and Don Mueang Airport each take just under a half-hour to get to when there's no traffic, but can easily take twice as long to reach during rush hour.

This hotel offers four categories of lodging: Cozy Rooms, Comfy Rooms, Classy Rooms, and Citrus Suites, with interconnecting options available for groups. Entry-level Cozy Rooms are small, and come with king-size or twin-size beds, while Comfy Rooms only have twin bed options. Classy Rooms and Citrus Suites are all king bed configurations and add bathrobes and slippers. Suites also add large living rooms with tables and small sofas. Rooms follow a blue-and-brown color scheme, with brown carpeting with blue squiggly patterns, bright-blue throw cushions, dark-wood paneling and matching furniture, and brown black-out curtains. Amenities are consistent across room types, and include free Wi-Fi, flat-screen TVs with satellite cable, coffee- and tea-making facilities, minibars, and safes that are big enough to hold laptop computers. Microwaves are available on request. Bathrooms are snug but pleasant, with walk-in showers with large rainfall showerheads (but no tubs). Hairdryers and toiletries are provided. Many rooms, particularly those on higher floors, have great city views.

This hotel has simple amenities aimed primarily at tourists. There's a naturally lit fitness center with city views, free weights, and a few cardio machines. There's also a a sunbathing deck on the roof -- but no pool. Breakfast is included in some room rates and is served made-to-order from a set menu available all day for guests who don't want to take advantage of the extensive morning buffet. Lunch and dinner are also available at set times, and smoothies, salads, and sandwiches are available throughout the day and into the evening. Room service is also an option, but it's not available 24 hours. There's also a small meeting room and Wi-Fi is free throughout the hotel. For guests with cars, there's a small parking lot. The tuk-tuk shuttle ferries guests to the main road, where there are plenty of shops, restaurants, and public transportation options. Airport transfers and laundry/dry-cleaning service are both available for a fee.
