Judy and Steve are the best hosts I've ever met before. I stayed at their house for two months. They are very friendly and I was impressed by their kind hospitality. Everything I needed was already prepared, and it was warm inside the house all the time even though it was freezing cold outside. They kindly told me the information about supermarkets and sightseeing spots.
I walked every day from their housing to Harvard University. It took about 9 minutes and it was very convenient to commute.
You can communicate with them if you want, but you don't need to do that if you don't want. In my case, I really enjoyed talking with them!
I want to revisit their house when I come back to Cambridge!
