The boat was exactly as described. it was cute, cozy, right on the water. The kitchen made breakfast prep easy, the bed was comfy, and the views were great.
It rocked a little when we walked on either side (it's a boat!) but it was not problematic and wasn't a problem at all when we slept.
It was a little further from the tourist area than other places we've stayed in Prague, but worth it for the charm and experience. We either walked or rode BOLT if we didn't feel like walking where we wanted to go.
I'm so glad we stayed here :)
