We've been trailer trash ! ;) I'm very interested in the idea of compact / nano living so this seemed an ideal way to experience that and see how much space is really required to live.
Booking and communication was reasonably smooth and we were quite shocked that we were told to find the keys on the table inside the trailer... What a trust... We arrived a bit early (a fun and very short trip from Central Station) and at the same time with a woman that claimed to be the cleaner and she told us to leave our stuff there and go and enjoy Amsterdam. We had no other choice than to trust her and we were happy to return in the evening to a locked, very clean and warm trailer.
It takes a few hours to get used to the compact setup of the place but basically everything required was there and functioned (the shower works the opposite way though). The level of heating for a good nights sleep takes a bit of experimentation (tip: open the bedroom window a bit for fresh air while heating mostly the living room) The second night we slept great and felt like sleeping in our VW van with the rain and storm hitting the trailer.
All in all it was a very convenient stay and definitely an experience. :) Any next time we'd know what to expect and we'd enjoy it even more.
