Aiyara Grand Hotel is located on Pratumnak Hill soi 6 near The Axis condominium. This is a new hotel, I believe it opened June 2011 but I am not 100% about the exact date of the opening. Aiyara Grand Hotel is a 4-star hotel with 180 rooms. There is a rooftop salt-water swimming pool. This is a very beautiful hotel, I drive past it almost every day and I always admire the design.
Aiyara Grand Hotel has started construction of a new wing or the second phase early in 2012 and construction will probably be completed by the end of 2013.
You can book a standard room with breakfast included here for only 2082 Baht or US$ 68.
