My original reservation was for 2222 Massachusetts Ave, but there was a mix-up with that reservation so they switched me to 11 Green Street at the last minute. This is arguably a better location except that the original location was very close to where my son is living. My room at 11 Green Street was quite small, with just enough room for a twin bed and a desk. But it was very clean and relatively quiet, and I felt secure with a lock on my room as well as the outer door. They gave me one free night to compensate for the mix-up, so I guess it all worked out OK.
