The reviews are all correct and Mark's apartment is perhaps the cleanest place I have ever stayed at and very inviting. It's located on the top floor of his home but it's very private with its own entrance and a vivid garden of flowers all around it.
Mark was a great host and even put on the AC for us before we got there to make sure the room was comfortable! He met us at the door and was extremely friendly.
The neighborhood is one of the nicest in Brooklyn and it was fun to just walk around and see the different homes in the area and people watch. If you're a film buff you can also walk down a few blocks on Smith Street to see where one of the key scenes in Goodfellas was shot.
The F train is a couple of blocks away and runs straight through all the major streets in Manhattan. There is no kitchen, but since this is located a few steps from Court Street, a number of nice restaurants and cafes are a short walk from the home. If you have a child with you, Books Are Magic, a great bookstore for kids, is also within walking distance.
If you need a place in the area you can't go wrong here.
