Juan was a GREAT host.. He went above and beyond, was very easy to get along with, and responded immediately to any questions I had. His roommate was also friendly, although we didn't see much of him.
The apartment is big and nice, with a traditional Brooklyn feel to it. The bed was comfortable and he gave us all clean pillows, sheets, and towels. There's no AC, but the two floor fans do the job just fine. He has Netflix on a big flat screen TV. The apartment is only a 6-7 minute walk to Dekalb avenue station, and an even shorter walk to the nearest bus stop, which was really convenient. I used both during my trip.
There's also a huge grocery store right on the corner once you get off the subway, which was useful to have there.
All in all, our stay was perfect, and I wouldn't hesitate to stay with him again. He went out of his way to make sure that we had a good time :)
