You will not go wrong with visiting Alex and Jas's place. It is situated very close to so many coffee houses, restaurants, bars and shops. And Domino Park is just a few blocks away, as is the subway where you can get into Manhattan within just a few stops. The apartment is exactly as described, very comfortable, spacious and well appointed. And the hosts are very gracious and quick to respond.
While staying here a few recommendations---coffee spots, my favorite was Devocion just a few minutes walk from the unit. They roast their coffee on site and the ambience is great. Other favorites were Copper Mug and Hungry Ghost, both just a few minutes walk. Restaurant recommendation for brunch would be Sunday in Brooklyn, a great oyster bar with many other choices was Maison Premiere (also interesting cocktails) and we enjoyed the Thai food from Tiger Prawn. There are so many options you will wish you had more time to try them all. It does get busy on the weekends, so reservations are a good idea.
The subway is a quick 7 minute walk and you will find all that you need within a few blocks. The area is vibrant and fun and enjoyable for any traveler wanting to explore outside of the city proper. You won't be disappointed.
