Pier's place is the perfect base for my friends and I whilst visiting Amsterdam recently.
It's close enough to the center but far enough to give u a little peace and quiet after a day of jostling at the city center.
The wifi is great and the balcony on the 3rd Floor is perfect place to relax and chill after a day in the center. There are trams that are close to the apartment, and there's even a nearby bus that one of my friends who had an early flight out took. It took her directly to the airport in about 30 minutes.
Pier is a gracious host and very helpful with our queries and not to mention, my very heavy bag!
It's a family home so the ambience is very welcoming. I would not hesitate recommending Pier's house.
