Note this was my first experience with AirBnB. I generally stay in hotels when I travel and never share bathrooms or living space with strangers. So this was unique for me.

The good:
Jonathan was organized and responded to the request very quickly.
The home was easy to find and close to Harvard.
The home itself is charming, including the loft bedroom.
Details on how to enter and exit (keys) were clear.
Shelves in the bathroom and kitchen were cleared if I wished to store belongings.

What I wish I knew:
There were at least 4 other guests in the home- including a crying toddler every night. This meant it was noisy well into the night. Considering I had classes to attend in the morning, it was not pleasant.
The room can get quite hot and the air conditioner in the loft bedroom is loud.
The bathroom was not cleaned while I was there for the 3 days (hair on floor, trash bin not changed, overall grimy etc). This type of thing is a major deal breaker for me and if had known about this, I would not have chosen to stay here. To be fair, I did not inform the host about this while I was there. I kept thinking it would be taken care of because it was advertised as very clean.
It felt like the home was run as a lodging business with all the different people there- I didn't quite expect that.

I think I'm just not the type to want to stay in shared accommodation for the above reasons listed.
