Joost was a very responsive host, always replying very quickly and answered our questions by phone during our stay. The apartment has a lovely modern kitchen and spa like bathroom.
The stairs are, I believe, common for The Netherlands, but were quite steep for us! (although nothing we couldn't manage). The location is outside of the busy city which was nice.
There is a wonderful bakery, a market, and a late night snack restaurant within a 5 minute walk which was really convenient.
It was unusually hot while we were there, so we took Uber mostly, so I am not sure how the transit situation is in terms of location. A ride to the town center was about 12/16 euro. Altogether a good stay , and I think especially perfect for a family with young children.
