Staying at Emrah's place was just perfect for us, great budget accommodation in the absolutely best location- right behind the Blue Mosque, walking distance to Topkali Palace, museums, Hagia Sophia, Grand Bazar etc....great restaurants all around, including the one below the apartment - Emrah's is a charming and very helpful host and as his carpet store are nearby- is always available to answer questions and assist and advise with tours etc.
And has a super comfortable queen sized bed- great after a long day of sight seeing :)
