We stayed in the apartment for 5 days with young kids. The host is amazing, very responsive, approachable, and kind as well. He welcomed us and also made sure that all remained fine during our stay.
The apartment is of high quality, spacious and even better than how it look in the pictures. The access is easy and the apartment has everything you need during the stay. It is also safe for families.
The location is amazing, just like 2 minute walk from Galata tower, in a narrow street with nice cafes. One coffee shop is just opposite the apartment and one cafe right next door offering various options for breakfast and dinner.
Overall we strongly recommend the host and his apartment and will definitely prefer to stay their during our next visit to Istanbul.
