Hi! I am coming to city w/ two teenagers for 3 nights in Oct. One day BU , one day Tufts, and the rest of our time will be spent sightseeing. We have no car and are on a budget. I have lodging choices in the $195 to $250 range. I want to choose the location based on convenience - so far there is Hyatt Regency Boston One Avenue De Lafayette - Courtyard by Marriott Boston-Tremont Hotel or Hotel Nine Zero 90 Tremont but I can keep looking. If I understand correctly the T will get me to/from airport and to the two schools fast & easily no matter where we stay? If true, then I would like to be closest to the most sights. Back Bay? South end? North End? Is Tremont Street hip & trendy? I was going to stay farther out as its cheaper but I want my girls to get a flavor of the city. Thanks!
