Reinout is friendly, has good tips about the area and is totally trustworthy. We accidentally left some money behind and he immediately notified us and was willing to try to return it to us.
His location is great! So close to the Centrum and we were able to walk to almost every place we wanted to go. Anne Frank Haus was close and it was about a 30 min walk to the Rijks Museum.
He also was quite hospitable, leaving chocolates, wine and some coffee and tea in the room. We really enjoyed our stay there.
