We had a very nice stay at Biriz's apartment. The apartment is small but functional, with everything we needed. The location is great, in a dynamic and trendy neighbourhood, with many restaurants, cafes and bars. Istanbul's old town and touristic locations are easily accessible with public transportation (tram, metro, bus). The area is quite loud during the weekend, we could hear the basses of the nearby clubs/bars at night, so we recommend ear plugs if you're sensitive to the noise. Biriz is very friendly, reactive and helpful!
