My stay at Raymond's place was wonderful. Mainly, Raymond is an amazing human being and a lovely and warm host, and it was such a pleasure sharing a space with him!! What a treat. :)
About the place: the apartment is clean and home-y, on the fourth floor of the building. The room was nice and comfortable, and I was able to work from there during the day (no Internet problems). The room also gets lots of light during the day which is awesome. It had everything I needed for my stay in NYC. The location is pretty decent, it's walkable to the metro so it's pretty easy to get around, and it's also within walking distance of the shops / food of park slope, but the immediate vicinity has more of an industrial vibe.
Would definitely recommend!
