Staying on Liz's houseboat was such a pleasant experience. She was very accomodating with our check in and had prosecco and treats set up in the room for us, as well as flowers the second day.
The room is spaceous and quiet, and the terrace off the back of the boat makes for a lovely relaxing place.
The houseboat is situated in a good area. Just out of the tourist area, but close enough that everything is walkable or easy to get to by tram/bus.
Would definitely recommend!
