We would normally price this space at $53 a month. Consider making a counteroffer to this host.
The guy was really nice, and the storage area was 9x9, but it was shared with the cats in the basement. I noticed after the first load I dropped off that the cats enjoyed climbing on top of the boxes and scratching them and leaving lots of hair. I made sure to surround the nicer items with cardboard boxes (that all ended up with many claw marks and cat hair on them). The pathway to the basement was very narrow and untidy, included walking under a low hanging and untrimmed tree. The private entrance is not accessible to the renter; we often waited several minutes for the guy to open up. All in all, cheap storage but there are better things out there for sure.
