First off, John was an incredibly responsive host and was willing to be very flexible. With that said, the space was not nice: the entry way is a walk-up without any hallway/stairway lighting, the apartment had a strong odor from the restaurant downstairs, I found many cockroaches in the bathroom and one in my bedroom, and there was a shared bathroom even though the advertisement led me to believe the bathroom was private -- this is further problematic because there are three rooms in a small apartment, each with two beds and only one bathroom for up to 6 people. I stayed in the apartment only to sleep and shower in the mornings, but this made traveling less relaxing without a comfortable place for downtime. If you are looking for a low cost space in Cambridge this might be a good solution, but personally I was not happy staying there.
