We stayed at Alper's apartment for a week during the New Year holidays. Istanbul was our family meeting point this year, so we were a large company of 6 guests.
Alper is a kind and responsible host. He shared all the necessary information about the check-in process in advance, ensuring that our arrival procedes smoothly. He also gave us an orientation tour around the apartment, explained the key information about the facilities, and shared advice about the city area around.
Considering the apartment itself, it is very spacious and sunny, with very convenient location. We highly appreciated the equipment of the whole apartment and particularly the kitchen. We could hold a festive New Year Dinner for our company without any issue.
The only concern that we faced was with the draining system in the bathrooms, but it emerged on the last day of our stay, probably due to the temporary issue of the whole building. Hopefully it gets solved soon.
Overall, I would recommend it for a stay!
