Alright, so I've stayed at a few Airbnb's in Boston as well as other areas outside the city and this is what I noticed.
First off, the location as one or two other folks mentioned is in a more undeveloped area than one would expect. I've been in worse and didn't feel uneasy but I can imagine some other people might be uncomfortable.
The check- in process was very easy and straightforward with solid communication from the host right from the start.
My room had 3 twin beds which was fine but unfortunately the lock set for the bedroom didn't work as it was loose so that was a little frustrating. For some that might've been a bigger issue.
The main complaint I had was the cleanliness of the bath and shower. It's difficult to see like 10 to 15 bucks of my money go towards housekeeping and then not have a clean place to "clean up". Also, I had the shower diverter cranked all the way and it was barely hot. Then literally maybe ever 15-30 seconds you lose pressure and what hot water there was would turn cold and would stay like that for several seconds ( plumbing lines not dedicated). It was pretty frustrating. I asked about this and didn't receive any feedback.
Another issue was the heat- omg 🥵 it had to be 85 degrees in the bedroom but John said it was central and couldn't adjust (t-stat in hall set to 67). So I cracked the window and kept it propped open all night with my sneaker but the noise from the street was pretty loud so that was a real pita. I'm going to stop there and leave it alone but I did not have a good experience. I'm into saving money if what I'm getting is decent but this place needs work.
