Greg's flat is well located in Brooklyn, just 2 blocks from different subway stations. His appartment is not only well situated but also full of light, the room is big and cosy. It is also pretty quiet for NYC. I slept very well although I am sensitive to noise.
As a host, Greg knows a lot about what's going on in NYC. He is very smart and friendly and gave me much appreciated tips about night life or various cultural activities.
I will definitely come back next time I visit NYC.
