This is a great spacious place 20 meters from Galata Tower. Location is superb, close to restaurants and major tourist attractions, a short walking distance to ferries or subway. The flat is enough to host 6 people comfortably (i.e. 3 couples), has all the amenities one can expect. There is also a big table and a separate living room - convenient if you want to dine at home or play tabletop games. The place is clean and well maintained. The only drawback might be if you travel with small kids - airconditioners are a bit noisy (but this is true in any place in the historic center of Istanbul). Overall highly recommend, much better than a generic hotel!
