We stayed for one week with three people in Serra's place in late September and found everything as advertised. Communication was prompt and check in a breeze. The area is great, close to everything and yet quiet at night.
Check out the reserve on the river bank b/w Grand St and S 5th St; awesome spot to hang out and watch the sun set and the Manhattan skyline come to life. There was also a Latin dance night on the Wednesday when we visited.
