We had a great week in Istanbul, the flat was perfect for us. We used the flat with 5 persons, 1 person used the couch for sleeping. The flat was exactly what we were looking for and as described by Mersin. To arrive from the airport by taxi at the flat, we gave the taxi driver the phone number of the assistant of Mersin and he found the flat immediately (and that is not the normal case in Istanbul, as we found out during the stay). The Istiklal Caddesi, one of the popularest streets of Istanbul, is very near and you can get there in just a few minutes per foot. Also Galata and Taksim aren't far away. Mersin was very helpful and stayed in contact. He always answered very fast. Thanks Mersin, we liked your flat and our stay in Istanbul very much.
