Had a fantastic one night stay at the FS in Bangkok in september.
Everything about the hotel is what you would expect from FS. The rooms are quite large and the finishes are quite high spec, the lobby is stunning as is the pool area (we didn't actually use the pool but used the shower area after checking out before going to the airport). The conceierge (?) were also willing to go that extra mile to help us during our short stay by booking resturants etc for us and taking delivery of a suit which didn't arrive until 2 am.. We would definatly recommned this hotel to anybody staying in Bangkok.

Some tips for your stay - if you can go and eat at BED superclub which has fantastic food and is quite a different experience and if you are looking to get a tailored suit use Embassy tailors which is used by the British and US diplomats (but dont let that put you off!) who turned a cashmere suit around for us within 15 hrs.

This property is perfectly located for shopping. The size is quite large so for groups and business it is also good. There are 4 restaurants, which are very good with great service. Throughout the hotel, the service is what you would expect from a Four Seasons. The fitness center is above average and the spa is outstanding!. Overall a great experience. The only downside is the hotel is a bit old and needs an overhaul. Would definitely recommend.

We stayed on the executive floor of the hotel and this was probably the best hotel experience we have had for many years. All the staff were fantastic and only too willing to go that extra bit to help. The girls on the executive floor were especially willing and able to help us on everything we needed. The breakfasts and evening canapes/drinks were especially well done and interesting. The bedrooms were always clean and tidy and little extras from the hotel were appreciated. When we left they even provided little plastic bags for the airport security checks! I would strongly urge you to pay the extra and stay on the executive floor. For a Four Seasons this hotel is also extremely good value for money. We ate in all the restaurants the Italian "Biscotti "really good original food and a very competent and effective manager the same kind of excellent manager is also in the steak restaurant "Madison" again great food this time based on meat/
steaks. The Thai restaurant is OK but not great (maybe bit too westernized food!!). My only complaint the price of wine but there again its the Govt duty not the hotel profits. We staryed for almost 2 weeks having extended from a week. Very relaxing and after a day in the Bangkok heat and humidity it was great to get into their pool and have a few beers or a drink in the lounge. All in all this is the best hotel stay for many years.

Excellent place. Unfortunately I only stayed one night, but would have loved to be there longer. The staff makes an effort of remembering your name (like in all FS's) and smiles all the time (seemingly genuinly).
Perfect location and excellent food. Very nice rooms with high quality furniture and finishing. Large pool with good service.
Overall much better that Shangri-La, which I believe is massive and less friendly.
I recommend this place for anybody wishing to stay in Bangkok
