My partner and I stayed at David's houseboat for two nights late April 2022. The lugar is a snug fit for two people, equipped with a sink, a table and a shower. There were some other guests staying at the boat at the same time, however, the entrances for the two guest rooms are separate. The houseboat is situated very centrally, and so you can easily get there by foot from Amsterdam Central station. David was a wonderful host, very easy to communicate with and super friendly.
