This is a lovely apartment: clean, comfortable and conveniently located close to Sultanahmet square and a metro station. Nahide is a gracious host who provided us with a tour of the neighbourhood when we got there and solid recommendations for things to do. She also provided us with a spare metrocard, which proved to be an unexpected boon as the subway system is very well- connected.
We stayed at Nahide's apartment twice in October 2015 and I'm glad to report that this approach was consistent both times. I'd recommend staying here for short and long trips alike.
