We recently had a great stay at Mayer. Communications from the Mayer team was excellent from start to finish; any minor issues that we had were dealt with in a very timely manner. The location of the apartment was ideally suited to our needs. Beyoglu is a great place to stay; located in the middle of all the sites and a fantastic array of bars and restaurants on the doorstep. The apartment was very homely, spacious and fully appointed as described in the AirBnB advert. The only negative was that because it is a first floor apartment, there was noticeable street noise until the early hours but this did not detract from our stay. An excellent apartment in a great location - we would stay there again on any return visit to Istanbul.
