I spent 5 months in Skylar's apartment. Overall, everything went well: the apartment is well furnished and as described. Greenpoint is a great and quiet neighborhood. The G and 7 trains are really close and make Manhattan really accessible. However, the place was not really clean when I arrived. Also, I would recommend to install an AC in the apartment. Even with a fan, the heat is really hard to bear during summer.
Skylar is a good host, but sometimes lacks of communication. He had to make visits in the apartment for a few weeks, which was not a problem for me.
