The apartment is nice and clean, there is everything that you need (except soap and detergent, which normally nobody carries anymore while travelling).
I would say that the apartment is suitable for not more than 3 people because the room with two single beds is too small for two people, there is no place to put clothes or something.
One more important detail - the entrance to the bathroom is super low, so a normal-height-person hits his/her head against the entrance door. In the bathroom a ventilation window is open, so it is really cold to take a shower.
Close to the apartment, it is difficult to find a free parking spot.
The owner of the apartment and a girl that met us are really nice and helpful, we did not have a problem in communication.
