    "Local dog parks are very nice . Even walking around on sidewalks it’s a nice place. Usually nothing blocking the way on sidewalks. Well maintained (besides the snow) not much we can do about that "

    "The rent is high due to the commercialization and the green line construction, however, if that is not an issue, then you might like it here! It seems like there are a good amount of community events, however, I work full time as a young professional and have not had the time to explore too much."

    "The new MBTA extension will pass through it making it easier for commuters to and from the area into Boston or Medford. It's still a diverse cultural experience with a grand Brazilian shop and other smaller shops (including the reliable market, that's been there for almost 40 years), to give the Square flair and connect many of its diverse residents. I also love the memories I have here, including the Dunkin Donuts that's still there. I also enjoy the convenience of getting into Boston through it."

In my city we have bikeshare, carshare services and uber/lyft and greencab. It is also cyclist friendly -- they have bike paths and bike sections on the roads to make it easier for these commuters."
