We stayed at Hikmet's apartment for five nights, and were comfortable there. It's located walking distance to the tourist areas (although you'll have to walk a few blocks uphill). We appreciated having a washing machine and kitchen. The beds were very comfortable, and everything was clean (daily housekeeping services are offered too). Future guests should know that the apartment does have a few minor maintenance issues that could be fixed to make the place nicer (back door leading to enclosed patio didn't lock, wires sticking out of walls and ceiling, walls need to be painted, random kitchen supplies and utensils, toilet bidet water runs constantly). Also, the apartment is on the lower level, so it becomes quite humid when the shower or wash machine is in use (and takes a long time for clothes to dry). Overall, though, the apartment is a good value, and Hikmet is a wonderful, kind host. He was quick to communicate, welcomed us with a large bottle of water and a plate of oranges, and invited us to a complimentary roof top Turkish breakfast. We had a very good visit to Istanbul, and would recommend Hikmet's apartment.
