My girlfriend and I spent three nights at Henriks and Frederiks appartment. Overall, the place was very clean, comfortable, in a great location and we had a great stay. What you're mainly getting is a small room, so if you're looking for a large space you might want to look for something else. However, for the two of us it was totally fitting. Additionally, there obviously is the living room, kitchen, etc., so besides your bedroom there's still plenty of space, just not "your own".
Fun note: while we were there, they were currently building their IKEA kitchen and we ordered ours a few days prior to the trip - so we got some free construction tips aswell :p
