Hein's place is GREAT! We stayed here for 3 nights and couldn't have asked for a better host and place to stay.
Hein gave us excellent tips for exploring the city and tailored it to our interests. He was always around during the day to say hello and point us in the direction of some awesome local spots.
The place was perfect for us. It had everything we could possibly need, plus some. Also, that bed is super comfortable.
Definitely book at Hein's place if you want something that is easy on the wallet and comfortable at the end of a long day adventuring around Amsterdam!!!
