I recently completed a stay at the JW Bangkok- a few points: 1. The lounge is one of the best in the system worldwide- excellent selection of food and beverages, great very attentive waitstaff, and a nice terrace overlooking the city. 2. Location is good- but not as good as the SGS for example- it is about a five minute walk to the BTS, which can be a pain in the rain. 3. Japanese restaurant Tsu Nami (unfortunate choice of name) is excellent- very good quality and beautiful decor. Currently there is a lunch special at 698 BHT which is a wonderful promotion- it is all you can eat including sushi, sashimi, and grill orders. Great service also. 4. Pool area- not one of the best in Bangkok- a little bit sad looking actually- however the gym is exceptional. Children seem to enjoy the pool however, and it is shallow (maximum 1.25 m). 5. Rooms- I am not a big fan of the Marriott decor- and this is pretty traditional Marriott in that regard- the carpet is a bit disturbing. My other feedback is that if you have a room facing Sukhumvit it is quite noisy at night. The closet is also far too small if there is more than one person. Bed is very comfortable. Service is also great from housekeeping. Water pressure in the shower is very strong- a rarity in most Bangkok highrise hotels. Would I stay here again? Maybe- although as it is priced similar to the Four Seasons, and higher than the nearby Conrad and SGS, it would be tough- definitely come back for the set lunch promotion however at Tsu Nami- one of the best deals in Bangkok for high quality Japanese food in an elegant setting. Staff are also some of the best in Bangkok.
