I would highly highly recommend Peter's place! Not only was it very clean and nice but it's so cool being on the floating house and seeing the neighborhood. I do want to note that Peter's place is about fifteen minutes outside of the main part of Amsterdam with the tram or a taxi being the only available way back to the center. If you plan to use Amsterdam's public transportation then you should 100% stay at Peter's and use the tram to get there and back. However, if you're looking to do mostly walking then Peter's place might not be right as it's 4 miles away from central station and not easy to get there on foot.
All in all, Peter was a fabulous host with a fabulous spot and I recommend to anyone looking for a very local/relaxed vibe while in Amsterdam.
