We had a great time staying at Devrims place. She got in touch with me almost minutes after accepting my booking and was extremely helpful the whole time. Right from sending me extremely detailed information about things to do in Istanbul in and around her neighbourhood to helping with other recommendations. She was there to greet us when we arrived and we loved the artsy homey feel she's created in her home. The shower was a little bit cramped but a small price to pay for this lovely home that we were so comfortable in.
This is definitely a place I'd like to stay in when I come back to istanbul. It's really well located too, with the tram and furnicular lines a few minutes away.
