We stayed at houseboat Nova for 9 wonderful days. It was raining most of the time we were there so we weren't brave enough to take the bikes out but we found everything exactly as pictured and described. The space was quiet and beautiful so we had a peaceful retreat to return to after a day of sight seeing and art museums. It is very convenient to tram and bus lines. One highlight was seeing a beautiful swan glide by at dusk. We never actually met our hosts but were pleasantly surprised that his mother stopped by to check on us.
I can't imagine a better place to stay in Amsterdam.
