I was in Boston only for a night. John's place is very close to Harvard Square, with excellent public transportation, very convenient. However, the place was not very clean. We came into the building and was overwhelmed with this strong unpleasant odor, possibly from the old building? I don't know. The bedroom was very simple, a bit old, and quite smelly too, not from smoke or anything...maybe just old? I don't live in a city like that so maybe it is just me. Anyway, there are definitely bugs in the bedroom, flying around and such. The room was a bit small, but I guess it is Cambridge and its proximity to Harvard Square... The bathroom was a bit filthy, so we did not end up showering... and tried our best to take care of business while we were at restaurants or some nice public restrooms. You can't use the kitchen unless with prior permission, I didnt need to use it so no comment.
One more thing that is kinda bothering me is that: so I took a red-eye bus to Boston. The bus arrived at 6:00am, so I requested to drop off my bags early... around 6:30-7:00am. I understand it was super early so when the host refused, I totally understood and ended up waiting around until 9:00 am to drop off my luggage. I got lost a bit because of new city...and Harvard Square T station was under construction and they moved everything around. Anyhow, I arrived later than the agreed meeting time of 9:00am, and John did not seem to happy. He was a bit short to me, but whatever...I didn't really see him anytime afterwards.
Overall, it is okay...but it does take about 50+ mins to get to downtown Boston by public transportation just FYI . Hope that helps. Happy Airbnb-ing!
