Where to stay in the Boston area?

I am relocating to Boston, MA for a new job with Pioneer Investments. I am having a really hard time finding a place to live since I am not there. So I ask you, where can I find a hotel that wont break the bank. I don’t care if I have to take a subway in to city center (no bus or commuter rail). I need a place for a week or two so that I can actually go find a place to live. I have tried reaching out on AIRBNB also but I am not getting any responses.
