Mehmet's place is 5-10 minute walking to the areas we wanted to see within few days in Istanbul - Hagia Sophia, Blue Mosque and Topkapi Palace. The apartment was on the quieter street, especially considering how busy the area gets.
Everything was great. Mehmet met us in the apartment, explained everything about the place, gave recommendations for local markets and send some more recommendation afterwards. He suggested few places to go since it was our first visit. Every day he'd check in to make sure we are doing ok, send a few more recommendations and wished us to enjoy our day. Even after we left and went to Cappadocia, he sent me a message checking up on us.
The apartment comfortably fit 4 adults and 1 child. We all had our rooms with plenty of space and the living room is a nice place for the family to get together and relax after a long day of walking.
