I stayed at Laurie's place for 9 nights while attending training at Harvard Medical School, which is within walking distance. The location is great: nice buildings, a Whole Foods and nice restaurants nearby, a few minutes walk to Charles River for running, and close to public transport.
I stayed in unit 1, which is close the laundry room in the basement of the building. Noise from the laundry or neighbors was not a problem; there is a busy street in front but it wasn't too noticeable in the apartment. At night the apartment doesn't get fully dark since there aren't (or I didn't discover) blocking shades. This wasn't a problem for me so I didn't investigate deeply.
I was very happy to discover copious delicious supplies for my first breakfast; this was a really nice touch and made me feel like on vacation. Thank you Laurie!
