I have stayed at quite a few Airbnb and this is one of the best experience I have had. Irene is caring but knows how to give you the space you need. She is a kind person who takes interests in the guest staying at her place.
Her home is very clean in a nice / safe neighborhood. I slept so well in the comfortable bed and the quiet environment. There is a Starbucks, a local bakery and a few good restaurants within 5 minutes walk. Irene offered to make the best coffee for me each morning and we ended up chatting while sipping coffee.
I enjoyed Cambridge and staying at her place is one of the highlights.
