We stayed at Dan's place for a couple of nights while in town for a friend's wedding. Although it's listed as just a "private room," it's essentially a whole private apartment with just the kitchen being shared. The apartment was perfect for us - the bedroom had a SUPER comfy bed and its own bathroom, with a desk and quick wifi that allowed us to get some work done. The attached living area had a very comfy couch, and would have been a great place to relax if we'd had more time to hang around the apartment. It's located on a residential street in South Boston, but is very close to main roads with plenty of restaurants. The wedding we were attending was in the Waterfront District, which was on the edge of walkable (~25 minutes) or a super quick uber ride.
Although we unfortunately didn't get to meet Dan since we were all over the place during our stay, he was super communicative and clear. He was flexible with our need for an early check-in which made life WAY easier, and left us some information on the area so we'd know where to go for coffee and food and the like nearby. Absolutely recommend him as a host, and would definitely stay here again.
