The arrival was perfekt, Sevgi had set up a helper, that we could contact from the airport, where she guided our taxi driver. At the appartment we was recieved by the helper, who showed us around in the appartment, helped us get in grips of excatly where in Istanbul we where, to use for future guidens, also she helped us with the metro map. so we where well suited for getting around. The appartment was fantastic, only thing, friday and saturday there is a kind of diskotec in one of the neightbour houses, loud music until 3 in night. However easy to work around.
All in all a fantastic stay, very satisfied. Thanks.
