If you are tired from standard hotel rooms, staying on Friedrich's boat Rosita is perfect choice. It was amazing experience for us. The room is not big but is very cozy and you find everything what you need there. Bed was very comfortable, kitchen was well equipped and everything was perfectly clean. The boat is about 10 minutes from the Central station and in walking distance from city centre. We did not need to use public transport at all. Friedrich was great, helpful and very friendly host. The communication prior our stay was extremely easy and any question was promptly responded. I can fully recommend the place.
