I stayed at Tolga's place for 3 days. I am originally from Istanbul so I knew in advance that the location was perfect. This is one of the best locations you can find in Istanbul for a touristic visit. Firstly it is very central: Taksim sq, the modern art and other museums and the old historic part of Istanbul is in walking distance. Secondly it is located in the trendy neighborhood Cihangir full of good restos bars and clubs. Finally the street is silent at night despite its central location. It is very safe as well - trust me I am from the city! Oh, yes, there is free wifi as well;) The apartment has everything you need for a short stay, it is very clean and nicely decorated. Tolga is very kind and helpful. You can always call him on the cell phone in case of need. I really have nothing else to say, don't hesitate to book it!
