We enjoyed lovely spring time in Amsterdam! The boat is located in very nice neighbourhood in a perfectly walking distance to the main city attractions. The size of our "floating boat" was exactly what we had expected after seeing the pictures. There are only two things I want to mention we didn't like :
1) tiny WC is located very close to the bed (in a wardrobe with a window)
2) everything was quite dusty... It felt like a cozy cottage where nobody cares to much about cleaning
3) heating is really noisy (floating water)
