Me and my friend can highly recommend this flat. We looked at a place to stay only 2 days before and Revsan was super reactive and welcome us for 6 days in her flat.
The appartement was really clean and convenient; The location is also perfect as you are close to everything and Taksim is a nice area to have a drink at night without having to take buses or taxis. We loved the city so much and can say that staying in her local flat made a huge difference for us.
The only thing was the fact that the wifi didn't work but all the bars offer a free wifi. The toilets was not working well which was not super convenient but I'm sure Revsan is planning to repair it. It was a great experience.
