This is a great spot for a quick visit to Boston, especially if you have plans in the Allston/Brookline/Brighton area. Other than that you could take a bit of a walk to the nearest T stop or easily Uber.
It’s spacious enough for 2-3 people, and from what I can tell was safe.
The parking is a huge bonus that you won’t get in any hotel.
For lighter sleepers, it’s definitely tough. You’re right on a super busy main road. I recommend ear plugs and an eye mask to try to stay asleep. The heat is also not controlled in unit.
Jessy/Diego were super responsive for any questions/ issues that came up.
