Basma was very nice to wait for us quite late and welcome us with some Turkish delights. The location of the apartment is approx. 30 -40 minutes walk from the main historical areas of Istanbul (Blue mosque, Haga Sofia), but in terms of Istanbul size it is quite fine. You can also get there in 10 minutes by tram. The location is also convenient for travel to/from airport, as it is close to the metro station which gets you straight to the airport.
