Sebastian is a nice host that is very accommodating and responds to messages in a reasonable amount of time. He and his roommate stay in their rooms for most of the day, so staying in the living room felt more private than I would have imagined originally, which is a plus. The location is unbeatable if you are rotating at Cornell's hospital (2 minute walk away). The closest subway lines are about 7-11 minutes walk away which is also not bad. There are several restaurants close by as well.
The space did get pretty hot and stuffy right when you enter because the living room did not have an AC unit, but Sebastian provides a sizable electric floor fan that kept me cool throughout my stay.
Overall a really great location with nice hosts!
