This was really a great experience!!!
As i know Prague pretty well, this was something that i didn't know and i highly recommend it to people wanting discover Prague from a different perspective.
The houseboat is well equipped. Additional you get a mobile phone and a small boat with an electric motor for trips on the river.
My stay during the cold season was no problem. Heating works perfectly. I was given a warm welcome by Marketa an Michael. They helped and explained everything. Definitely one of my favorite addresses for stays in Prague.
