Ingeborg and Renze are excellent hosts and we had a lovely stay on their boat. Prior to our stay, Ingeborg was kind enough to provide us with useful info on events happening in town on that week-end. Renze welcomed us on board warmly and was available when we needed. This is not your typical houseboat. Sachsen-Anhalt is a proper vessel, but is comfortable as a house and equipped with everything you need. The location is central enough (10-12 mins tram or bus ride to Amsterdam Centraal).
I would happily recommend Ingeborg and Renze to anyone, and stay on their unique boat again if the occasion presents itself!
