John is a great host. He is kind and friendly. He has been many places in the world and is very knowledgable. I stayed at his place for about two months. We often have a beer together and talk about things over dinner. It was an extraordinary experience.
The location is also good. It is 2 minutes' walk to the 77 bus route (go directly to Harvard) and 10 minutes' walk to the red line subway station. There is CVS and Trader Joe nearby. The neighborhood is very quiet.
I highly recommend staying at John's place.
