It is indeed an spectacular and high standard houseboat! We have spent 5 nights in a family trip, and we have absolutely no regrets. The boat is perfectly located in a vibrant neighbourhood full of good restaurants and close to the main touristic points. Nicole was kind enough to leave us their bikes which is a fantastic way to move around the city (although riding a bike in Amsterdam requires some attention!). She left us a complete guide with very helpful information about the boat and great tips about the city. In addition we had some very nice treats when we arrived: Dutch cheese and a sparkling wine.
We had very pleasant evenings sitting on the deck watching the boats crossing the Amstel. In summary, we highly recommend this houseboat. Needless to say that we would definitely go back!
