We had a wonderful time in the appartment of Javier. We stayed there with 5 persons and had enough space. For us it was perfectly situated as we did not only want to be in Manhattan (which is easy to travel to as the Subway is nearby), but also in the more authentic part of Brooklyn. The appartment is comfortable and fully equiped. Javier responded quickly to any question and is a very friendly host.
Some closets are a bit messy and the cleaner could have done a better job, but nothing to really worry about.
Overall we would reccommand Javier's Le Chateau Boutique!
