I loved staying at Boris and Susan's. It is a short very short Lyft or Uber ride to the blue line and to the airport. I was nervous about using the subway since this was my first time in Boston and I was traveling alone, but it turned out to be the easiest and cheapest way to get into the city.
At the end of they day, I was happy to find the entire house incredibly clean and tidy. They offer some delicious snacks in the room and in the kitchen. I was very pleased with my stay.
