I am running the Boston marathon 2013 and am looking for a place to stay that is close to the subway or t-rail because I can't afford the cost of the back bay hotels. We are looking to keep costs below $150 p/nt. I have 3 family members travelling with me and they would like to have easy access to the finish line, whereas I need to get to the start line. We are travelling from California into Logan Int'l airport hopefully from April 12th - 16th. Any recommendations?
