I stayed at Pieter's canal house with two friends for a week while on vacation in Amsterdam. I can't recommend it and the host highly enough, and I would stay again in a heartbeat.
The house itself has three stories plus a basement, with two bedrooms, 2.5 baths, and a large couch in the living room that's as good as another bed. (I should know - I slept on it the whole trip and refused my friends' offers to rotate beds!) It's spacious, beautifully furnished and maintained with classic Dutch architecture and a large library of classic books, and lets in as much natural light as you could ever ask for. The exterior deck is icing on the cake, and we spent several evenings there during the week.
The house is situated on the inner edge of Jordaan, a bustling central neighborhood packed with shopping, bars, and restaurants. It gets busy during the day but quiets down at night, so noise from the streets and canals was never an issue. It's also right off bus and tram lines, though we rarely used them since a 20 minute walk would get you all the way to the center of the city. I really couldn't imagine a better place to be situated for a stay in the city.
Pieter and his wife and son were perfect hosts and extremely easy to work with. They communicated fast, gave clear directions and were able to give early access to the house to drop off luggage prior to check in, and dealt with small issues that arose gracefully and conscientiously. I wish all my Airbnb hosts were like them!
tl;dr: awesome house, awesome hosts, awesome neighborhood. Our Amsterdam trip owes a lot to how much we enjoyed staying here.
