This is a very comfortable apartment in the very center of Istanbul. If you are a tourist and want to see the main sights of the city, this is the best location. You can walk to Sultanahmet Square, there is a tram stop and the subway station nearby.
The apartment was very clean and heated and there was always hot water in the bathroom (we are from Bodrum, this is a miracle for us). Hikmet was very helpful and waiting for us, gave clear instructions and we found accommodation easily.
We highly recommend this apartment and the owner.
