Great place, great host. I was staying while visiting Harvard and the location is perfect for this: just off Massachusetts Ave with lots of eating options, and only five minutes walk to Harvard Square for more. It is on a quiet residential street off the main roads, however, so no noise issues at all.
I was warned by Je before booking that she was yet to finish decorating the place, and wanted to make sure that I was okay with that, and that she had adjusted the price accordingly. Her idea of "not finished" was a few blank walls without paintings, so she clearly sets herself a very high standard! At any rate it was perfectly fit out for me as it was: nice space, nice furniture, comfortable bed, the heating and hot water all worked well, very warm even during a cold snap and snow day in Boston, etc. I couldn't have asked for more, but she is, apparently, working on it more yet!
Je was very communicative, and both check in and check out were smooth.
Highly recommended!
