We stayed in Mahsa's place for 4 nights. We absolutely enjoyed our stay there entire time. The place is very well located, we can access to anything easily. A quiet spot in the bustling Istanbul. Communication with Mahsa is smooth and she always responded quickly.
The apartment itself is well equipped too and spacious. If I have to pick one thing, the bathroom is very small, but it didn't bother us at all. We recommend Mahsa's place to everyone!
