I only stayed here basically to sleep. The kitchen is well-equipped, but I did not use it.
The location is great. There is a bus stop right across the street that takes you to the Kendall/MIT T stop.

It is clean and well-kept. The neighborhood is good. The only concern I would have is if you are a little older. The pullout bed is a queen size, but you are sleeping about 8 inches off the floor. If you have arthritis, it could be challenging to get in and out of bed. There is an elevator to the second floor. There also is no cable TV. You need to provide your own content, or figure out how to get over the air digital TV.
I did not need to contact the host, but their directions were very easy to follow.
I would definitely stay here again.
