Place is great, spacious and lovely. Three tips though: stairs (we were fine with it, but it is an issue), small amount of cold water in both sinks (after cold water there is hot boiled stream so it’s difficult to wash hands or dishes) and low ceilings in bathroom and bedroom (again, we were fine with it, you can get used to it totally).
Location is almost city centre, Galata is just there. Neighborhood is friendly, lots of shops and cats.
