We stayed 2 nights on Titus' houseboard. It is a beautiful historic boat, with original woodwork and features. It is walking distance (approx 20-30min) to the city centre and one can also get trams and buses nearby. As one expects from such unusual accommodation there are some quirky features including a couple of short steep stairs/ladders. The accommodation was clean and had everything we needed for a short stay. Titus was friendly, helpful and relaxed. We had a really good experience.
