Deniz (the host) was amiable and responsive. On a few occasions, we needed some information and he was accommodating.
The house is located really close to Galata tower which is a really lively neighborhood. It might be a bit difficult to reach if you have suitcases since the area has lots of ups and downs and you have to navigate among cafes and restaurants and tourists.
The check-in and check-out were automatic which gave us freedom and not to worry to bother the host.
Our house was located on the last floor. Unfortunately, the house does not have an elevator and the steep stairs might be difficult for elder people (or with heavy suitcases,...)
The house was really clean and spacious. Can accommodate easily 4 people. All rooms have air conditioning and heaters. The kitchen has all the essentials.
We really enjoyed our stay and fully recommend this place.
