The room is in a great location in the center of Rotterdam. The host was very communicative and the check-in was satisfyingly simple. Unfortunately, we did not find the place very comfortable. The mattresses were very hard and the ones on the bunk beds too thin. Also, inside the studio it was a lot smaller than we had pictured, nobody could stand next to the sink if someone wanted to go to the toilet.
If you're planning a party weekend in Rotterdam this is definitely a great place to stay otherwise it might be best to keep looking.
