Bill and and his co-host Corey are seriously the best hosts ever. What they offer is by far more valuable than the rate they're charging you to stay in their extra room. The pictures of the place don't do the room (or the house) justice. The plants they've grown are beautiful, and the abundance of beautiful paintings throughout the home are an added plus! Our plane arrived late and we didn't get in until 11:30 pm on Monday. Corey stayed up and corresponded with us from the moment the plane touched down, to the warm greeting and late night tour of the home once we pulled up. The walk was about 3 minutes to the Subway, and there are plenty of great spots to grab a bite around the neighborhood. Throughout the stay, they offered breakfast snacks, sodas, water, and coffee (all replenished the next day!). They were very accommodating, even during the initial messaging phase. The bathroom is stocked with clean towels and washcloths that were cleaned every day and replenished for the next morning.
Bill and Corey were also very informative about many things Boston related. Whether you're looking for things to do, or food recommendations around town, they've got you covered. Bill also used to be a tour guide, he's got quite a bit of neat facts related to Boston that we would've never known otherwise.
TL;DR - You're missing out if you don't stay at this airbnb. Also, during your stay take time to get to know Bill and Corey.
