I can't say enough good things about our recent stay at Peter and Katja's Blue House. They are great hosts: very helpful and welcoming, and genuinely warm and friendly people. The little house overlooks their backyard, and there were multiple opportunities to say hello or exchange a few words, while still offering plenty of privacy. The house itself is cute, comfortable, well appointed, and immaculate. We took every advantage of the available bicycles to explore the city and some nearby attractions on the excellent bicycle transit system. I don't know if we will ever visit Amsterdam again, but if we do, I wouldn't hesitate to book with Peter & Katja again!
