We had a similar experience to some other people who have stayed here - the apartment itself is very clean, but is on the smaller/older side with thin walls, a cramped bathroom and a steep 5-floor walk up. We had some issues and confusion checking in - Gonzalo was responsive when this was happening but did seem inconvenienced. The location is right in the heart of Williamsburg, which is great and makes it easy to travel to Manhattan as well.
