My wife and I stayed in Anne's flat for two weeks while we visited Istanbul for the jazz festival. The directions to the the flat were very good and collecting the keys was simple. The flat was simple, comfortable, as described and everything worked. The written instructions were very comprehensive.
We enjoyed fixing our own breakfast and light meals as well as enjoying a cup of tea on the large sofa. Just the roominess of the flat was nice for such a long stay. The location was perfect for getting to many concert venues and city attraction as well as walking to Taksim. Although it is so central, the area has a real neighborhood feel to it with small shops, kids playing in the street, vendors coming by and the other people watching street. There are also lots of street cats that seem to fed by everyone in the community. It gave us a real feel for the city.
Lastly, I would like to prairie Anne's attentiveness as a host. Any question that we had, she got back within an hour. The preperation was well organized and well thought out.
