Our stay was perfect! Close to one red light window, but we definitely felt safe and were in a great area. The houseboat is close to the central part of town, and we ended up walking most of the city (which we recommend). Really good food and shops nearby.
Our communication with our host was great- no problems whatsoever.
There is a swan that will greet you in the morning, whom we named Ralph :)
Would definitely stay again!
