The location of the apartment is very convenient to get to the tram/bus/metro station, it's very close to the sea and to the Sultanahmet major sights. There are also a lot of small shops around.
The flat is actually nice: there are all necessary things for comfortable stay. There is proper air conditioning inside which is very good in summer. But it seems to be not so clean as I expected, which was a bit bothering.
But Sermir was very hospitable and ready to help with just anything I needed, which is very great)) It made my stay in Istanbul very comfortable and safe. The check in and check out was also very convenient - thank you so much!
