Everything was great! Perfect location, useful guidance and assistance from the hosts, and the room was very comfortable (and secure).
Hard pressed to list any cons, but if I had to I'd only mention that the bed was on the firm side (which wasn't a problem for me, but might be for others), and the hosts did as good a job as one possibly could to address the local climate, which could get cool and damp in the evenings.
Overall it was an excellent experience for my first AirBnB. I wouldn't hesitate to recommend the listing, and I hope to book with them again the next time I'm in town!
