Really a great place to stay! The room is nice and clean (maybe a little bit smaller than it looks on the photos, but that's really not important), the bed is super comfortable and the neighbourhood is quiet. The location is very good too: there are two bus stops within 3-4 min walk, both going to the train station in less than 10 min (we had our flight back at 8 am and managed to get to the airport in about 35 min). There is also a tram that goes to the museum quarter and Anna Frank's house is 15 min away by foot. We spent most of our time exploring the city, so we didn't see our host a lot, but Diewert was always very quick to reply to the messages and his wife was very welcoming when we arrived. There is also a folder with a lot of useful info and maps in the room!
