We really enjoyed our stay at the Cavehouse! It was in a fantastic location. The place was super cozy and extremely clean. We came in the winter and there was heating in both living room and bedroom. There was hot water in the shower all the time which was very important for us. The sheets smelt freshly washed and the host provided tons of towels and extra sheets and went above and beyond with leaving toiletries and extra items. There was also very fast wifi. I highly recommend you to stay here when you visit Istanbul! :)
