We had such a lovely time on Merel's houseboat. It's in such a perfect location - just far enough away from the very centre to not be too busy - but close enough to feel right in the action. It's definitely in a supremely picturesque part of town, and sitting on the deck enjoying the boats float past was a particular highlight. The room is quite small - and the bed in particular very cosy (too cramped really for two people) - which in the height of Summer might get a little stuffy. Overall it's worth the stay and definitely a fun place to be for a couple of nights!
