We are a French couple and we spent 3 nights at Kevin and Annmarie's place, with 2 teenagers.
We really enjoyed the house, where we felt like at home.
The house is very nice and clean, with much space. Kevin and Annmarie welcomed us very kindly, offered us muffins, orange juice and other things to eat and drink when we arrived, and they gave us ideas of places to visit, restaurants etc... The house is located in a quiet street, near from Harvard and MIT, and from the red metro line. We will come back !
