This is a lovely lovely hotel.
I went there together with my bf for a weekend trip to Amsterdam. Since he's a big art fan, I thought that this place could be interesting. We were a bit sceptical because we usually go to the bigger chain hotels but our fears were completely unnecessary.
Museum Suites is a lovely place at a great location. The owners are very nice and helpful. You can see the care that they have put into every detail in your room (we had the Vermeer Suite).
It is super clean and quiet and just overall a great experience.
