Birgit's houseboat was the highlight of a wonderful trip. We stayed there for 7 nights, and I wish we'd had more time.
The boat is exactly as described - bright, open, clean, airy.
Birgit provided us with a "starter kit" of food, including milk, bread, cheese, eggs, bacon. There was also coffee and tea. It was great to have food that first day. The Copenhagen Harbour is at the south end of the city, and we rented 4 bicycles for the duration of our stay, It took us about 20 minutes on the bikes to get to the boat from anywhere we visited in the city.
