In short, our 9-day stay at this place was very pleasant and everything was great.
A deltailed review: The check in/out was done smoothly, the communication before/during our stay was easy and Erdal and her sister, Adife, were very kind and responsive. The place was and maintained clean all the time, equipped with the stuff we needed.
The location is central, in a walking distance (7 to 10 mins) from Sultan Ahmet touristic site, in a quiet/ family oriented neighborhood, close to various restaurants, grocery stores, cafes, etc. Walking between 12 to 20 minutes, one can get to any means of public transportation, bus/metro/tram.
Above all, the hospitality and amiability of Adife and Erdal made a memorable accommodation at their place for our vacation, for which my family and I are really grateful.
