We stayed two nights in August while it was very hot. We never met Muge as a local older woman housekeeper let us in to the apartment. There are many stairs so you need to get strong help to take any heavy suitcases up.
The studio is simple and clean. The room is small but it was convenient for a short stay. The AC is good, and it is right above the bed so blows on your face at night.
While the street isn’t very charming like Istanbul it is very good location for access to Taksim Square, ferry, bus and train.
