I highly recommend Geraldo's place. The apartment is huge for NYC or actually for most places. It's in the back a few stories up for quiet. The bathroom is amazing - shower and tub and lots of towels. The kitchen is small but I cooked for our meals most days. The host was quick to respond to a couple of questions and check in was very easy.
The location is wonderful. A block from Union Square. Definitely visit the Green Market - a large farmer's market with great produce. And many subways stop at Union Square so easy to get around. Finally, Irving St is near by with many restaurants and bars.
The apartment made for a memorable week in NYC.
