The heated outdoor pool should be enough to qualify it for 5 stars.
The rooms were in excellent condition and the lobby is amazing. The elevator up to the lobby lowered my expectations but I was pleasantly surprised once in the hotel. Very nicely built and easy to get around.
Room service was quick and the food was better than most hotels. We didn't try much but it was all good. Prices are reasonable for such hotels, nothing crazy. The food in the lobby restaurant is great and I really liked the bartender. Made perfect drinks.
Locations is great. We walked to most places. Metro is attached to the building and you can walk underground to most malls.
