One more option is to use the Boston airport, and Amtrak your way there. You'll need only one bus from the Amtrak station to the Boston airport (Silver Line express bus). It's not necessarily better or worse than the other options, depending on how well the timings, train, and airfare work.

CA White's very good, and their studios start at $1090 though you'll have to contact them for actual availability: https://cawhite.com/apartments/

Might try Marco Polo. Ain't New Haven style or anything fancy, but does the job.
