We had a wonderful time on Rosita. The boat is charming and extremely comfortable. We arrived in the middle of a heatwave and Friedrich was kind enough to supply us with various fans. The boat does get warm, however I think 36 degree heat is unprecedented in Amsterdam! Freidrich was kind and helpful with lots of local tips. He was around to ask advice but left us to our own devices. The area of Westerdok is also lovely. Really peaceful but really close to the station and transport links. We would highly recommend a stay on this boat.
