Staying in the houseboat was immensely enjoyable. The location on the river is very good: quiet and private but not remote. The marina is secure and the waterfront felt entirely safe (if almost eerily quiet). The houseboat itself is modest and appealing, and the interior in particular is very charming. The space is a bit tight as you would expect, but never feels closed or oppressive. A good layout (including separate rooms for shower/sink and toilet) and lots of windows (with effective blinds) maximize the space. The view of the river is nice and very relaxing, if unspectacular, with various river animals cruising by intermittently and even some fish jumping when it rains. The sinks, shower, and toilet work well and are no different than those in a hotel. Be aware that you have about a 12- to 15-minute supply of hot water for the shower, which replenishes fairly quickly. The space heater works well, if slowly. Cooking wouldn't be easy, but there is space inside and outside of the cabin for preparing or eating food.
These are some of the nuts and bolts of staying in the houseboat, but these details fail to capture the sheer joy of spending your nights and mornings in such a fun, unusual, well-designed accommodation. From the very start, it was a delightful, almost magical experience, right down to being greeted by a pair of swans when first arriving. Daniel and his assistant were effective and communicative hosts; Daniel in particular went above and beyond the call of duty to be helpful. Only possible cautions: thin mattresses and a mildly unpleasant odor in the shower room. Get the WiFi password before you arrive and buy some public transport tickets beforehand, since there are streetcars much closer than the metro. But I emphasize that these are mere afterthoughts. The houseboat was an excellent choice and an even better value. If you like the photos or just the idea of staying in a houseboat, I strongly recommend that you stay here.
