The apartment is a 3-bedroom, 2-bath, with two nice and easy-going Harvard grad students in the two other rooms. You would have the master bedroom, which has its own bathroom and is really spacious. The kitchen has everything you would need to cook with. Right outside of the apartment there are nice restaurants and public transportation options, and it's a 15-minute walk to Harvard.
The location is fantastic, in a safe and quiet neighborhood yet really close to Harvard campus, Harvard Square, and Union Square. Also very close to The Biscuit, a great coffee shop down the street, Dali tapas restaurant, and The Forge bakery.
The Harvard Square T stop and Porter Square T stop are both about 12 minutes from the apartment by walking.
