I really enjoyed my stay at Alberto's apartment. It's quite spacious, bright ( windows are in every room) , stylish and has everything u might need for a comfortable living. Even though it's been pretty cold in Istanbul during our stay, the heating worked perfectly and it was worm and comfortable in every room.
The terrace and the view are just amazing. But yes, be prepared to use the stairs to go up to the 6th floor - it wasn't a problem for us (really great every dayexcercise), but might be a problem for some people.
Alberto is a great host. He responded quickly and he's helpfull and really pleasant to communicate with.
Thank you!
