Parking garage, off street parking?

[cerylium.livejournal.com]

I have never owned a car in boston, so sorry if this is an obvious question to ask.

I have someone interested in renting my room but who has a car.  My apartment does not have parking, and this person wants off street parking.  I know there are odd spots advertised on craigslist that one can rent, but are there any garages in the area where you can rent spots?

thanks!
