Boston doesn't have apartment complexes like TX, rather there are multistory houses where you rent. If you are looking for an apt with parking expect about 12-1600 for 1bd room. Its not cheap. You want to be looking around Somervile.Medford,Watertown or Cambridge. There wont be any covered parking spaces. Only big apartments have them and their rent starts around 2500. What is your budget? I would suggest you to get a shared apt.
