Pros: A very central, clean and convenient place with high ceiling which looks bigger than on the photos. Great explanations & smooth check-in. (In case you wonder, there is a bag locker nearby which can come handy if you know about it. We didn't test it).
The beds were very comfortable. Adam kindly let us check-in earlier which was much appreciated. It's a good place to stay in if you're there for a few days.
Cons: The wall between the two adjacent apartments lets all the sounds pass through. Quite inconvenient if you're looking for intimacy (can hear all conversations and tv) at night.
There were unimportant little problems with a couple handles which weren't holding in place. We didn't mind at all and I just let Adam know about it. Unfortunately he seemed to imply that we were responsible for it. This didn't make us feel comfortable.
