If you're looking for a weekend getaway to Amsterdam this is a lovely place to stay; outside of the city centre but close enough and with good transport links that it doesn't matter.
It's airy and deceptively large, the host is very friendly and helpful; she gave us the lay of the land and how to get about Amsterdam.
I'd definitely recommend it as a place to stay, but it may be more suited to a spring-autumn visit as it's a little cold in the winter.
