We had a fine stay in this guesthouse. The location is great, close by to shops and lots of restaurants and you get what you pay for in terms of the quality of the room. Our room had a double and single bed, aircon worked well. Wifi was unreliable (stopped working for about 12 hrs at one point).
Little things like no cover on the shower drain (just a hole), shower taps that move in the wall when you use them and an old towel used as a curtain in the bathroom do make the space feel a bit run down.
All that being said, it’s cheap, in the centre of town, close by the bus to the airport and the air conditioning works well. The host also kindly allowed us to store our bags after checkout until our flight. For a night in Istanbul it’s a safe bet.
Host was uncommunicative through Airbnb app ( and I had to message for information about check in etc), but responded quickly on —WhatsApp—.
