First have to say that Hans was very welcoming. We arrived later in the evening and no problem at all for Hans. He happily greeted us and gave us a complete tour of the space at 11:30 in the evening. Really liked the welcome book with suggestions for things to do and places to eat and Hans provided water and a bottle of wine. He also checked in on us after a day or two to ensure all was well.
The space was great. Location on the Herengracht was perfect for us. Easily walkable for all parts of Amsterdam's Centrum area. Also, close to the city's excellent transit resources. We found the accommodations to be perfect for our stay. Very clean, well appointed space. Everything you needed to be comfortable for visit to Amsterdam.
