Our stay at Berith's was really pleasant; the place was superb, the room is really spacious and colourful, I really loved how she furnished it, her personality is definitely reflected in the way she decorated the house (:
Also, the house was spotless and perfectly cleaned.
We were also really happy about the location, you can rent a bike for 11€ a day just down the road, and with the bike the city centre is only 15 minutes. We spent a lot of time in the north part of Amsterdam, some really nice places where to hang out and avoid all the tourists. Totally recommend it.
