Great place! First, let me say I've never felt more welcome. Kemi is an excellent host who proactively communicated details and was very responsive. Getting in was easy with keypad access. The place is cozy and combines a lot of the amenities of a hotel (like shampoo and body wash dispensers in the shower) with a nicely decorated and equipped home. I have pretty simple needs - cozy bed and a coffee pot, this place was so much more. Decent size space, a desk in the dining area and snacks (which I happily ate after a long day at work). The place is near the T, near great dining choices and near many of the businesses and universities of Cambridge. Quiet location and convenient.
If you are new to Cambridge you should give it a try - Kemi had a binder with things to do locally and I learned a lot after being a Cambridge regular for over four years. Highly recommended.
