We had a great stay at this hotel. Everything was well taken care of: clean and comfortable room, good breakfast, perfect internet via wifi, nice (small) pool on 6th floor, awesome view from 6th/7th floor, very friendly and helpful staff.
We arrived in the middle of the night because of flight delay. We were hungry, still they managed to get us a good meal at 4am via room service.
Close to the hotel there are lots of shops, restaurants and street sales. Grand Bazaar at 100m. Blue Mosque and other ancient sites were on walking distance. 50m from the hotel is a tram stop (Beyazit). 10 minutes walk to the Vezneciler metro station, which takes you to Besiktas with line M2.
