Does anyone have some recommendations for budget-friendly lodging that is close to a T station? We're not wanting to be much more than 30 min.s from downtown Boston. We have pretty specific needs as our son's girlfriend (17 yrs old) will be traveling with us so will need her own room and bath and we want a king room with pull-out sofa bed. Using lastminutetravel.com etc. doesn't seem to be an option as those rooms are typically the standard doubles and/or not guaranteed configurations. We're looking at VRBO.com and homeaway.com as well. We'd like to keep the entire lodging cost to be $1500 or less. Our dates are flexible through June and July but looking initially at June 17 - 24th. Thanks for any help.
