I loved my stay at Daniela's place. I was in town for a month for work and this was a great place to come home to. It's spacious, quiet, and stylish (I loved the exposed brick). The location right next to the subway (2 minute walk) is extremely convenient for getting downtown via the 6 line.
If you're a runner, this is a great base for exploring the city. Central park is easily accessible and you're a few blocks from the bridge to randall's island.
I'd recommend staying here, especially if you'll be spending time on the East Side and want great park and museum access.
