We (2 persons) stayed for 6 nights at one of Ayla's apts - #101, one flight up from ground floor.
The apt is very spacious and has everything you would need. The refrigerator is large size, and there is even a clothes washer. The one thing we did not like is the bathroom flooring - it is very dated and appears to be dirty.
There was plenty of hot water for showers for the 2 of us.
The location was good for us, we walked most everywhere we went...coming back at the end of the day taking a taxi was difficult though, if we were able to get close to the apt it was when we were dropped off at Galata Tower...most would not even take us that far due to traffic and very crowded streets.
Ayla was very prompt to answer my what'sapp questions, and assisted us with getting a PCR test and results before traveling. Thank you, Ayla!
