This boat is a must! What an amazing experience. We were a group of four people, and we stayed for 4 nights. The check-in was very easy, and Patricia was a great host during our days there.
The boat is very close to the tram/metro/bus station, about 7 minutes walk. From there you can easily get to the city center.
They have a kitchen with almost all you need to make dinner and have a great time.
Also, they have a nice deck where you can probably enjoy the nights (we couldn't enjoy it very much because of the weather).
Hope to have another opportunity to stay at Kay/Patricia's boat one more time.
