I stayed at Justin's for 2 nights. Loved the cleanliness, spacious, private space. It had a great kitchen area and several comfortable sofas. Another plus is it's wonderful location! I enjoyed walking to Harvard Square (20 minutes) for lots of restaurants and entertainment. There is also a lovely bakery and coffeeshop a few minutes walk from the apartment. Justin communicated well prior to check in, as well as checked in to see how things were after I settled in.
The bed was large, clean, with lovely bedspread and decor. Only note is that if you like firm mattresses, this might be something to consider for a longer stay.
Would definitely recommend Justin's place for your stay!
