I would definitely recommend a stay here for the value. The room was spacious with great amenities. It was great having a mini fridge, sink, and microwave in the room. The bed was cozy, and I loved having a lounge chair to relax in and a desk to work at. The bathroom is well appointed, and I got to try out a rainwater shower for the first time. Mort (or Jeana) responded promptly to all of my messages and were lovely hosts (despite not having met them in person). When I was chilly my first night, I was provided with an extra soft, warm blanket the very next day.
There were only two minor cons that I found. The first is the location - it's not a lovely neighborhood for dining, shopping, or just walking around in. This is partially my fault, as I didn't research the area. I was there for business anyway, so it was fine for me, but I found it necessary to get an Uber pretty much every where. Still, the price point of the room was low enough that I ended up saving money (even with paying for rides) compared to staying in a more central or touristy location. The second con was the noise from the unit above. I'm not sure if it was a long term renter or another AirBnB traveler, but I heard more of them than I would have preferred (nothing too crazy, just loud talking, laughter, and footfall like an elephant). Luckily, I had ear plugs and a white noise machine to drown it out, so it wasn't a huge problem.
If you decide to stay here, and again, I WOULD recommend it, just be sure you're armed with ear plugs (and white noise if you're a light sleeper) and be prepared to take a car around the city. You will otherwise be very comfortable in the room and happy with the value in Boston.
