Allen and Anne are super sweet and excellent hosts. The rental is just a bedroom on the bottom floor of their beautiful restored brownstone, which they also live in. However they are happy for you to use other parts of the house e.g. the kitchen - and invite you to join them there for bagels and coffee each morning! (if you would like) Note that while I was staying there, my bathroom was shared with a guest renting an adjacent room, but this didn't prove an issue.
The location is excellent, very close to downtown brooklyn, and it's a great value.
