We've returned here twice; it's a great location for city explorers who want to walk around, see the city and do all the tourist stuff and some shopping.
It's 10 mins walk to the Skytrain/Metro interchange (and Terminal 21's great food court) and you can easily get to even further away places like Chatuchak, Chinatown orthe Taksin river pier (for river taxis, Wat Pho etc), The three types of room we've stayed in have all been meticulously cleaned and are furnished to a high standard. You can choose a simpler room, which is still very spacious, or basically a mini-apartment. We found the staff courteous and helpful, and there were many happy-looking guests.
It's slightly hidden away down Soi 23, not on the busy highway, but then you'll see more of the real city, For example you can walk to the beautiful shop of family business T Shinawara for the finest Thai silk or just some very affordable Thai handicrafts suitable as small gifts from about 50 baht (it's hidden away - check their website location page.) Or, you could just grab a fresh coconut or orange juice by the Shell garage for 20 baht, zip off on the Skytrain to explore, and then have a drink on one of the street bars below the enormous video wall at Asok on your way back! Good access to all shopping areas and sights and about 45min to the airport.
They are improving the pool area at present, it's really nice anyway, but it was always open and had a relaxed atmosphere. There's a gym and Japanese restaurant, but we didn't use these.
A large buffet breakfast caters for diets of most continents, with eggs freshly cooked to your liking. There was plenty of choice, nice fresh fruit, and some apparently very hungry guests which is usually a good sign! Buffet breakfast drinks are the usual unexciting leaf tea and filter coffee, and the juice was very sweet, but they'll make you fresh coffee at extra cost or you can get a great coffee/iced drink at the stall at Asok station and watch the traffic below from a quiet corner of the walkway.
Check out the Sukhumvit area on websites and if it sounds like it's for you this is a good option.
