I had a great stay at Giorgia & Ben's homebase and I only can repeat what many airbnb-traveller already said: the host is very relaxed and let you do your thing but if you need any assistent or tips they're always there or reachable and very helpful. Williamsburg is a great place, the subway is only just around the corner and you're only 2 stops away from Manhattan. Even if Giorgia and Ben often working from home you always have the feeling that is really no problem and ok to move free in the small basement apartment. But - as also said often - you should love dogs, as it's always a loud welcome if you come back to your apartment. If I'm looking again for something perfectly located related to public transport I definetively will ask them again as you can reach really each point of Manhattan, Brooklyn, Queens ... with only one changee of subway line.
