The flat is very well connected, as the JMZ lines go directly to the city, and the J line goes as an express train during rush hours. ~20 minutes to Lower Manhattan, ~30-40 minutes to Midtown.
The flat was really quiet, more quiet than expected. A pleasant surprise. (The AC was a bit loud, but since it was really hot and humid outside that was something I endured gladly)
The kitchen is well equipped, you can cook something small easily, or have breakfast. There's space in the fridge for guests.
Communication with the host went fast and uncomplicated.
