Revsan was a huge help to us from the get go. She immediately answered all of my messages, was nice enough to come pick us up and drop us off, and kept in touch the entirety of our stay to make sure we were satisfied. Her apartment was very central, bright, and neat. The neighborhood was certainly quirky enough not just for a tourist but also a Istanbulite like myself. I'd definitely recommend her to everyone. The only thing is that the apartment is on the 4th floor and there are no elevators, so beware if you have weak knees.
