I highly recommend Nikita and Joya's place:
* Location: The place is in the perfect location if you're visiting MIT/Harvard, or other places in Cambridge. There are also plenty of places to get food/drinks within 5 minutes' walk!
* Check-in any time: Guests can self check-in and the hosts' instructions to do so are clear.
* Responsive hosts: Communication was easy
* Comfortable and Clean: The house and room are what I expect for the price it's at. No complaints there at all.
