First, to clarify if it is not evident by the property posting, this is a private room in an airbnb which has 7 or 8 rooms which are all rented out separately. There are two bathrooms which are shared between all guests that happen to be staying there at any given time. Access to the property and rooms are granted by key codes. Though it is a shared space, it felt rather secure, and I rarely encountered other guests.
I was taking a short trip to Boston on my own to conduct some research during the daytime and do some sightseeing in the evenings. This place had everything I needed for an activity-packed trip for one: a bed, a small desk to work at, space to spread out my things, access to a bathroom, a lock on the door, and a space heater (as this attic room gets a bit chilly). There was also a nice little water cooler and small fridge to share things with the other guests. Mostly needing a place to sleep and occasionally work on my laptop, this place fit my trip well.
The location was also great considering the reasonable price. This place cost about a quarter of what most hotels in Boston cost, and you can hop on the subway and be within the heart of Boston within 20 minutes. It was a short walk to the Lechmere subway station (6 blocks or so) which I felt pretty safe doing on my own as a young woman. I would recommend arriving for the first time during the daylight if possible, as the streets are not very well-lit. (Also keep in mind that it starts getting dark around 3:30pm in the winter!) After getting used to the walk to the subway station, I felt comfortable adjusting my route to walk on the streets that had more streetlight and activity.
I was also very impressed with how quickly the host responded to my messages. Check-in instructions and a description of the property were sent to me in a timely manner and were clearly laid-out so that I knew what to expect.
If I was traveling with others or if I had planned to spend leisure time at the airbnb, this may have been a tight fit. There isn't a kitchen or a common space, so if those are important to you, you'll want to find another place. However, if you're looking for a simple, affordable solution with a place to rest your head, store your things, and be well-connected to the city, this is your place!
