We stayed at Elif's appartment for 6 nights.
Elif was very reactive to our messages and answered them quickly.
The appartment is spacious, it is located at about 15minutes walk from the metro stations Taksim and Sishane.
There's a strong smell of cigarettes that bothered us (since we don't smoke).
The heat works well but the water's temperature changes from cold to hot all the time and the shower's door needs reparing.
We were disappointed on our last day since Elif promised to book a taxi for us to go to the airport but it never showed up.
Over all it was okay for the price we paid.
