CorporateFinancier: For my last interview I stayed at the Omni New Haven which was not exactly affordable, but was very convenient, allowing me to walk to my interview. I stayed there because Round 3 interview invites were sent exactly three days before the interview date and everywhere else was booked.
If you or anyone else is interviewing on 10/27, I'm staying at a great AirBnB this time with two bedrooms and a separate living space. I'd be willing to split it with one other person (contingent on the host being okay with this) if anyone is interested. I reserved the room for two guests. Anyone interested, shoot me a message. I'm a male, if that matters to anyone.
