The location is excellent especiallyy for tourists. Probably one of the most central places to stay, easy to reach everything, but not too crowded or noisy (just one bar downstairs on the street).
The hospitality was excellent. The staff were super friendly, flexible, helpful and had really good English.
The only drawback was that the room was a little tired from wear & tear, and the amenities (plates, glasses etc) were really limited, which made it hard to have breakfast etc.
Perfect place if you're looking for a base that's central and you're keen to spend your time out and about in Istanbul.
