I chose Peter's boat as a surprise for my wife. I could not have been more successful in my choice. My wife kept using the words cozy and cocooning. In fact the only problem was getting her off the boat.
It is also hard to emphasize how ideal this particular location is. Most other canals are not nearly as beautiful or quiet. This area is near the centre without the traffic of canal tour boats and nighttime noise. It is fantastic.
Peter was a great host. I could see how he would be extremely helpful to someone new to Amsterdam but he equally did not overwhelm us with suggestions since we are very familiar with the city.
