Marijke is an excellent host, she makes you feel welcome and answers any of your questions. The room is perfect for 2 people, 3 is a stretch but manageable. The top bunk is a double but very close to the ceiling so it can get hot at night and you can be prone to hitting your head if you sit up too fast.
The bathroom is large a spacious and is more than enough.
Location wise it is within a 5min walk to the train or tram station getting you into the city in about 10min. It's quiet and has local shops near buy for most of your needs.
Definitely recommend for 2 people to stay in, possibly 3 if you don't mind being cramped a little whilst sleeping.
