Kevin and Diane were great hosts, and South Boston is a great place to stay if you want to be near downtown and have easy access to public transportation. When we arrived, Kevin greeted us and gave us some tips for where to eat in the area. South Boston is very walkable, and we found many great restaurants along Broadway. We didn't really see Kevin and Diane for the rest of our trip, as we were there on business, but they communicated via Airbnb and provided for anything we needed, such as an iron and ironing board.
The apartment was separate from the rest of the house, so we had privacy, and the neighborhood was quiet, so we had a peaceful night's rest. The apartment was very clean and tidy, and had just about everything we needed. (The only thing I found lacking was that there was no mini-fridge for storing snacks, but that wasn't something they advertised, so that's no fault of theirs.) Overall, we had a very pleasant stay and I'd recommend it to any of my friends.
