The staff was wonderful. All of my trip planning emails prior to arrival were answered immediately. The staff helped with all transportation, tour recommendations and sent us to delightful restaurants. If you wanted, you could let the Ava team plan your entire Istanbul visit and you would have a great time. The hotel itself is comfortable. We stayed in an Garden Suite on the 1rd floor. It was roomy and quiet with a big nice garden. This isn't a 5 star hotel officially, but it provides everything you need beyond 5 star hotel quality. Good value, no risk.
