I stayed at the apt for 3 days for a conference at Bogazici University in Nov 2022. The apt is clean, convenient, decently equipped, safe, located in a vibrant area with lots of restaurants and bars very close to the Bosphorus, with all you need for a short stay. Communication with the host was very easy; thank you. If you arrive late and / or don't have a Turkish SIM card, make sure you read the instructions to get the keys beforehand; it is straightforward but requires knowing where to find the keys. The only downside mentioned in another comment is that the area does get quite noisy in the evening due to the proximity of bars nearby. I stayed in the room at the back so was not bothered, but if you need to occupy both rooms including the one facing the street, you should expect some noise until about 11pm or midnight (not much afterwards). Overall I had a good experience and recommend the place if you want to stay in this area.
