Mehmet’s place is ideally located to explore the old town of Istanbul. It has a beautiful view onto the Bosphorus and is lovely and quiet at night time. The bed is very comfortable - exactly what you need after a day walking through Istanbul. Mehmet is very friendly and accommodating.
If you stay with Mehmet I recommend that you ask him to send you a google maps link, it’s a little tricky to find on google maps otherwise.
