Thanh is very responsive. The place is well equipped and clean. We particularly love the kitchen as the stoves are gas and not electric and all kitchen amenities are available.
Neighborhood is quiet but we feel safe staying. 20 to 35 mins to Boston downtown depending on traffic.
BTW, although it is a house, everything is on one floor. Which is great and it is very spacious and tastefully decorated as per photos. I have no hesitation recommending his place.
