Just writing in English, such that all possible future guests can understand :)
Alekz is a very responsive and helpful host. Initially he tried to help us getting an early check-in, but when our plans had to change, there was also no issue we would arrive at 2am in the night since the check-in is simply with the doorman.
The apartment itself is pretty small, but nice and really clean with all the necessities one could desire. Also, the location is wonderful, as it is right in the centre of the city.
Definitely a recommendation!
