Stayed at Marie Claire's place for a couple of days, and it was just perfect !
The place is quiet, clean, well-organized with a superb roof top where you can enjoy nice evenings until the sun goes down.
If visiting Amsterdam, it is also perfectly located with 10 mins walk from the city center and direct access to all necessary shops.
I'd definitely recommend this gem, and would not hesitate to book it next time I come to Amsterdam.
