Kantary is a good and modern hotel, the rooms, actually apartments are well equipped and spacious. There is a nice swimming pool and gym on the roof top, that's a big plus.
The food from room service is very tasty and the breakfast good as well, egg station, fruits and wide choice of hot dishes.
The hotel has too building, one very close from a noisy road so better to stay in the main building, the one with the lobby and the pool.
The hotel is a nice gateway to go to visit ayutthaya or if you stay for business but you will need a taxi to move around, not many things to go at a walking distance from the hotel.
I will be back to Kantary for sure.
