I stayed at Behlül's place for one month in May-June 2022. I can absolutely recommend the apartment - it is one of the best possible locations for exploring the city and enjoying the nightlife. The apartnemt itself is perfectly suitable for a single traveller or a couple, it is clean and quite cozy. Although the apatment lies in a central location in Cihangir, the street is relatively quiet. Even though because of the thin walls you can occasionally hear ome sounds from the neighbouring apartments, it is not troubeling - I had no trouble sleeping and working in the apartment. Behlül was an excellent, welcoming and helpful host - you can expect your messages and inquireis to be answered in a very short time and if you have any needs, Behlül is very ready to help. He even helped me organize my journey back to the airport as I had to leave in the middle of the night. I would aboslutely reccomed the apartment.
