I have backpacked all over the world, and this was one of the best locations for the price (considering I was with my wife and we didn’t want a hostel). The metro was directly across the street, and only 3 stops to downtown - 2 stops to the aquarium.
The place was pretty clean.
Noise wasn’t too bad. You can hear the neighbors above walking, and people walking up/down the stairs in the hallway. However, I’m a light sleeper, and had no issues sleeping through the night.
The neighborhood felt relatively safe. A few bars and restaurants near by, but we spent most of our time downtown.
We would not hesitate to stay there again if visiting Boston for business or pleasure.
Interning question about Boston metro train stations....when all of the train turnstile entrances say “smart card” but you only have a paper ticket, how do you get past the turnstile? :) LOL.
