The location is really good. Quite quiet and safe area. But at the same time easy access to all attractions. There are the public transport stops within walking distance. There are also several supermarkets nearby. The apartment was not as clean as we expected. There was also a cigarette smell in the apartment, but after a couple of days it weathered.
And keep in mind there is a metallic bed in the right bedroom. And it's very creaky. When you roll over you will wake up. And most likely all your neighbors, too :)
Except of that everything was fine.
By checking in Volkan's friend even helped us with our luggage (the staircase is really high and steep).
