We had a very nice stay in Istanbul at Ece's appartement. The appartment is very well located, less than 10mn walk from the Galata tower, in a very lively neighbourhood and the nearest metro station "Sishane" is 1mn away.
The communication with her was very fluid and reactive. She was a very convenient host.
We were living in the first floor apt, which was very well decorated and clean, even if it looked a bit smaller than in the pictures. The only negative point was the bad smell in the bathroom due to humidity and some mold in the shower. The check-in was through a safe automatic box and we've been able to store our luggages after the check out time.
Perfect for a short stay in Istanbul, to discover that beautiful city.
