Is this just some random apartment building in Arlington? It looks like it's pretty far from the Red Line. If I had a city commute and was relocating. I'd try and find someplace with a one-seat ride to my final destination.
Plug the address into the MBTA "route planner" to get an idea of the commute & costs.
It doesn't look like an easy commute. Close to a mile walk and then a bus and then a train!
I have no idea what/where 360 is but I used to live in East Arlington and it took me just shy of an hour. On a per miles basis it was about as bad as it could be. I never thought to use a bike back then but it would have been much quicker. Some of my time was because my office in Boston wasn't right next to a red line station though.
Commuting from Arlington 360 (which I assume is this: http://livearlington360.com/ ) to ANYWHERE on public transportation would be a nightmare. At best you'll be able to time your commute with the 67 bus to/from Alewife. That route is notoriously unreliable, especially in the winter when it is regularly diverted onto the snow route, and doesn't run at all on weekends. Good rule of thumb for Arlington: if you don't live close enough to Alewife to walk there, plan to commute by car.Edited: 1:56 pm, October 15, 2015
Or maybe you meant take the car to Alewife? That probably makes sense in a lot of cases.Edited: 4:30 pm, October 15, 2015
I know this is coming a little late, but hopefully the information is still helpful. The #67 Bus now stops up at Arlington 360 and connects to Alewife. It goes right up into the complex and runs about twice an hour, during rush hour. You can also pick that same bus up on Summer Street, at the bottom of the hill from the apartments, in case you miss it on the way up.
Another option for commuting into Boston, depending on where you work, is the commuter rail. The West Medford station is about a 10-15 minute drive and the monthly pass costs the same as the T pass (and includes T access), so it's a good deal. From West Medford, you're one stop into North Station. From there you can walk, bus or take the Orange Line & Green Line to just about anywhere in Boston. And the driving to/from West Medford is significantly better than going into Alewife, which is a nightmare in rush hour.
Welcome to the neighborhood!
