I had the pleasure to stay in Gijs' place for 2 nights with 2 friends. We love the place so much!
The house/space is nicely located in the city, not far from the train station and easy for us to walk around.
The ground floor is nicely decorated. Feels like an art exhibition. The room (the whole of first floor) is spacious and is filled with reading materials which are mostly related to art, a plus point for us.
As a host, Gijs (and his partner Angelo) were great! Friendly and down to earth, he provided us with great breakfast and recommended us on whats going on in the city, where to go and what to do.
Art lovers or not, his place is just downright awesome! We hope to come back here again the next time we're in Amsterdam :)
