Pros:
Kitchen well equipped and upgraded
Fits a lot of people - three bedrooms plus two pull out couches
Walking distance to two fantastic neighborhoods (Inman and Central Square) with great restaurants
Onsite parking
Cons:
Quite noisy. Cultural center next door, busy auto traffic, noisy upstairs neighbors. Bring ear plugs.
First floor so had to keep shades down for privacy. Noise from upstairs (even just walking around) sounded like it was in our unit.
Type, quality and comfort of furniture was relatively low There isn't a great place to hang out for conversation or reading (e.g., couches were oriented so you could pull them out to put more people in).
Bottom line, best suited for reunions of large numbers of young people rather than middle aged or older people who want more creature comforts. I'm not familiar enough with relative prices in the Cambridge/Somerville area to know whether this is what to expect at this price range; maybe I'm being unrealistic given the price. So it's OK, not great.
