The property is very clean. It is located in a very nice, quiet residential neighborhood, surrounded by Harvard Campus . It is convenient to go to nearby bakery and grocery store, both within a few minutes of walking distance. With a little longer walk, over the other side of the Charles river, there is the Harvard Square.
There is a shared bath, living room and kitchen. Guest is discouraged from making food though. It is ideal for a solo trip (like in my case), maybe less so for a group. e.g., family.
Host makes sure that the guest has all the information absolutely required. You'd not expect Host to proactively approach, but if you have specific ask, you need to bring up and will get attention.
