This was a good little flat for our 10 days in Istanbul. Garen was kind enough to arrange a transfer from the airport and was there to greet us when we arrived. He walked us round the flat and explained how everything worked. Also before he left he emailed some recommendations for restaurants and clubs in the nearby area which was helpful and one of the restaurants we ate at twice.
The flat had three good sized rooms and was well lit despite the lack of natural daylight that was able to get in the flat. Each room had an air conditioning unit if required and even without them on the flat was warm to come back to at the end of a chilly day. Having a washing machine was also a plus.
Initially the neighbourhood is a shock by "western" standards but you soon get used to it. There is a small supermarket nearby and Istiklal Street is just 5 minutes away.
