Excellent location in Cambridge, well-within walking distance to two metro stops (Lechmere on green line, Kendall/MIT on red), which made it very easy to get around Boston. Safe area. Great host, very hospitable, and her cat is super cute. Note: You do have to climb stairs, and if you're very tall the ceiling might be a bit low for you, so watch your head! Shared bathroom, but never had issues getting into it when I needed it.
