Hein made our first trip to Amsterdam excellent.
When we fire got there, he let us keep our suitcases in his space before check-in, and gave us plenty of local tips for the area for food, drink, and sights. We were out practically the entire time, so we did not speak much, but he was always around if needed.
He also took great care of my girlfriend! She was very under the weather the day we were to leave, so he made her tea and gave her medication to take with her.
The space is exactly as described - it's small, clean, and has temperature control. Perfect for people who just need a place to sleep, shower, and drop their bags.
I'd stay with Hein again in a heartbeat if I ever came back to Amsterdam. We'll see you again, my friend!
