Stayed at Alex's place in May 2015. Just as described in the listing. It was new, modern and very comfortable. Master bedroom in the basement also gave some privacy from the kids :) The space was fairly large and comfortable for a family of four. Parking was on the street but ample parking which was a big plus. I understand that the area is not the best if you speak to Boston folks but we thought the area was just fine - a short drive to anywhere in Boston. There was perhaps an issue that there were no eating places/grocery stores we could see within walking distance but since we had a rental, that was not an issue at all.
Overall, great stay. Alex was always available to help but we since everything was well set up, we didn't need any help !!
