Lucas and Bori weren't able to greet us but their friend Pieter stepped into the breach and explained all about the flat and how things worked. The apartment was smaller than the pictures represented but by no means pokey. The bathroom is quite narrow but fully functioning. Location-wise we were just 15 mins away from the center by tram which was great, especially for the early start to join the queue for the Anne Frank House. We were very comfortable in the apartment and enjoyed shopping at the local supermarket for food and provisions, although less able-bodied people would struggle with the steep steps up to the second floor - we could barely get our suitcases up!. I would definitely recommend the flat to a small family (there were three of us). More detailed info about the nearby square with its shops and restaurants would have been useful. I couldn't access the information Lucas had put on airbnb from my phone while staying there and only discovered it on our last day.
All in all though a good apartment, ideally located and very comfortable and clean.
