Had a wonderful time at Ugur's place for my second time in Istanbul. He even gave us a free early check-in. Very quick to answer to messages and also gave us cool spots to visit, where to go shopping. Place is perfectly located, 4 minutes to Istiklal Street and nearby very authentic and hipster shops, cool cafés and restaurants. Ugur owns a pizza place so if you're a pizza lover have a try, I guarantee you will like it.
Also the bed is very comfortable!
