We stayed three nights and the houseboat is placed on a nice quite place at the Amstel river. It takes by bike 10-15min (normal speed) and by metro approx. 15-20min to central station. Mark welcomed us to Amsterdam and his home quite nicely and we enjoyed the time. Near the houseboat is a café for breakfast and few restaurants for dinner, also a supermarket if needed. We def. recommend this place for everybody who likes quiet nights at a unique accommodation with a quick and comfortable connection to the city centre and also the countryside like Utrecht (easily reachable via Train from Amsterdam Amstel).
