We stayed at Tiffany's apartment for 7 days and had an enjoyable stay. We didn't actually meet Tiffany, but we did meet her co-host Crystal, who met us at the apartment for a late night check-in, due to changes with our flight. We really appreciated the flexible check-in time.
As far as location and value for money, you won't find a better apartment in NYC! Literally a 5-10 minute walk from the subway and Roosevelt Island tram, so it's really convenient to get pretty much anywhere in the city.
The room itself was a lot bigger than we were expecting and had great views out over Roosevelt Island and into Manhattan. The apartment is high enough up that there is basically no street noise, and Roosevelt Island itself is a beautiful, quiet place to stay. It definitely makes you feel removed from the chaos of the rest of the city.
The shared bathroom could have been cleaner and the shower did not drain well. That being said, the shower had hot water and good water pressure. The wifi in the apartment was fast and reliable. We didn't use the kitchen, but it looked to be well equipped and reasonably clean.
All in all, a good value option in a fantastic location for exploring NYC.
