Our stay at Melissa's was GREAT FUN! It felt like a home, not a hotel. It looked exactly like a place where someone actually lives, and rents it out as an Airbnb when she is away. Melissa was amazingly responsive--within 15 minutes every time, and usually within 5 minutes--even though she was very far out of town on her own vacation! Also, the booklet that she wrote up of things to see, places to eat, how to work *everything* in the flat, was much, much appreciated! Very cool and cute space, comfortable bed, and just generally a fun place.
Easy tram ride to the center of things (Rijksmuseum, Red Light district, Van Gogh museum, et cetera). Definitely recommended.
--NOTE: The other reviewers are not kidding; the stairs up to the third floor flat are STEEP and NARROW. Definitely need to be in reasonable physical shape to get up and down them with suitcases! But, worth the effort!
