Marcel is really a good host, super nice and always available. And he can speak a lot of languages, which is really nice of him.
the rooftop is a dream, and the room has every comfort you need for your stay in the beautiful Amsterdam. the location is perfect, next to canals surrounded by nice bars and restaurants. Dam is only 10/15 minutes walking, one of the most central parts of the city.
Certainly coming back in my next visit to Amsterdam!
