Nan was a great host--the place was spotlessly clean and very comfortable. I was driving into Cambridge, and Nan lent me a guest parking pass which is SO helpful in a place like that where parking can be a total nightmare or expensive for a visitor. I was on a strange schedule since I was just popping in and out to do some work and Nan was very flexible about my arrival time. Also worth it to note that the room had its own entrance from the back so I felt very comfortable coming and going at my leisure.
