Natalie ... as far as I can tell, there are 2 commercial listings and 8 rental listing in the Mission Hill area ... Assuming that you're looking for housing, the rentals range from $2550/mo to $5000/mo and some are occupancy only and some may include some other stuff, most do not include parking. For exact details, we would need a link or an address or at least a photo of some sort.
I do work for tenants and would be happy to help you. Let me know if you need assistance. (617) 308-6583.
