We stayed here for a week. Taner and Nicola were very responsive every time we reached out with questions. The location is a 10mins walk to Istiklal street but on the more residential side of the main road. The wifi was sufficient but a bit slow if you are looking to work, we couldn't take video calls but otherwise it's good. The room was a bit chilly since there was light snow a couple of days. on those days the heating wasn't sufficient.
overall, a great stay, especially if you plan on staying here during summer
