Really lovely place - the roof terrace was a real bonus.
Good distance from the centre of town, so you're removed from the tourism a bit, and in a more authentic feeling part of Amsterdam. Still just 30 mins walk to the centre though, and because it's so flat, the walk is very easy.
We only saw one of the hosts at the start of our stay to get the keys, but we were contacted a couple of times just to check all way okay - this was just the right level of interaction.
All in all, we really liked it, would stay again, and would recommend to other travellers!
