Daan's boat is very centrally located. We stayed with three small children (9,4 and 2) and there were no issues with safety at all. The boat could accommodate up to 4 single adults or three couples, but the beds would be a bit tight for the latter. The facilities were very good and given its excellent location, it was still relatively quiet at night time. There is also very good access to the tram network from the boat with the No. 14 going straight to the Westermarkt and Anne Frank Huis and a little further long nearer to the Muntplein (perhaps a 10 minute walk) the No. 16 goes directly to the Museumplein (in behind the Rijksmuseum, Steedelijk Museum and van Gogh Museum). There are several restaurants and eateries in the neighbourhood, with the Rembrantplein only a 5 minute walk away. However, with the good access to the trams virtually on the front door step, you can safely venture further a field and eat in other parts of the city and still get home in comfort as we did a couple of times. Daan also helped to arrange an excellent taxi driver who drove us to the airport at Schiphol for around 45 Euros in morning traffic. The driver was punctual, drove safely and his vehicle was also very clean.We would recommend Daan's boat as houseboats are quintessentially an Amsterdam icon and a really cool way to stay in a fabulous city!
