My wife and I had a fantastic 5 night stay at Erol & Emre's place. The location is great. Very close to lots of nice restaurants and bars etc. The main shopping district is close by. There are also a lot of small boutiques and other interesting shops. It is also really well located a 2 minute walk to the subway, & fenicular which takes you to the tram or ferry. The space is very cosy and clean. Emre was an amazing host and very attentive. He gave us lots of local and recommendations for our stay and offered free laundry service for our clothes. We would definitely stay here again if coming to Istanbul.
