The place will be too small for 3 people. For 1-2 perfect.
Stayed here in winter - the most unpleasant surprise was that the heaters were off when I came in. With temperature -5 outside, it was not much warmer inside. It took the apartment almost 2 days to warm up and for me to take off 2 pairs of sweaters. I understand that they're saving up on the heating, however, it was said to be cleaned on the same day I arrived, a few hours before - they could've been turned on.
Very thin walls - could hear neighbors coming in as if next room and the bar with loud music.
A nice touch were 3 small water bottles. I also liked that the apartment is all white, just like in the pictures.
