I met Joost briefly, which is alway nice. He left keys to us, he told us quickly about the do's and don'ts.
The place was clean. One of the rooms had one big double bed, the smaller room had two beds that were a bit small, but totally fine.
Everything needed was there, it was cosy, nice neighborhood, very calm. Easy to get into down town, very convenient. I can recommend to stay at his place:)
