The upsides were: comfortable beds, good location, and a self-check in option for late arrival. The downsides were: low water pressure in the shower, and the old building irritated my mold allergies.
What soured our experience was a damage liability dispute with the owner. When I went to open to curtain above the sofa bed, (gently, I might add!) the wall mount came crashing down. It looked to me that someone previous had broken it and attempted a quick fix. I could have done the same quick fix, but since it was was right above where my head was when I was sleeping, I alerted the owner of the situation so she could fix it properly. Given how easily it fell out of the wall I didn’t believe this to be my fault, but nevertheless the owner came at us hard for damages and Airbnb had to get involved to mediate. In the end we were not charged, but it really added a level of stress to our vacation.
