I really enjoyed staying with Susan and her husband at their spacious loft. The apartment also doubles as an office as they organize the Brooklyn Film Festival.
I would have liked to have talked to them more about movies and the festival, but they were busy and I was out a lot of the time as well. Still, Susan was very friendly and helpful in suggesting how to get around town.
The location is a great if you want to explore Williamsburg and go out for food and drinks. It's quite close to Bedford Avenue, which is sort of the main street with many bars, restaurants and shops. It's also about a 10-minute walk from a train station, so it's easy to get into the city. I spent an afternoon seeing the sights in midtown Manhattan and got back early enough to meet for drinks and dinner with a friend in Williamsburg.
Although it's close to a subway station, I would still suggest taking a taxi from the airport. It's about $50 - $60 from JFK, if you go by car service.
The room is lovely with a lot of character, as well as a comfortable bed and big-screen TV.
It was also great to have a bathroom to myself.
Be aware though, if you plan to make food in their kitchen, they don't have a microwave and they have a gas stove. But there are so many cheap-ish places to eat nearby that you shouldn't have or want to eat in too much.
I would definitely try to stay here again when I'm back in Williamsburg.
