I booked this hotel through booking.com
I had a single room. The hotel is impeccable. The staff are all pro's. This is part of the Swiss Hotel chain. Clean, modern, bright and definitely worth it's 4 star rating. Nice bar on the ground floor, with a little courtyard in the back. The breakfast is a little pricey @ 20 euro, but nobody is forcing you to take it. You are a hop and a skip from museums, Leidseplein, park, swank shopping. It is perfectly located for me; away from the stoner college students in the city center. I will go back. No second thoughts.
