The room is bigger than the average in NYC, spacious, with great light and clean.
Williamsburg is a great location, great restaurants, trendy bars, lots of nightlife.
The metro is just one block away, about 2 minutes walking, and taking it you can reach the heart of Manhattan in 10/15 minutes.
Charles has been a great host, I didn't have the chance to meet him but he was always in touch with me and always available for any question.
This was my first Airbnb experience and was really positive.
