Staying at Nick and Tiffany's was amazing. The place, although somewhat far from Manhattan, is really well connected to the subway system and it was an overall comfortable experience. Installations are nice, well put together and clean (except for a few days but that depended on a couple of temporary housemates).
The kitchen is fantastic.
Only downside would be that we had to share the only key available for our room of two, which I hope gets solved for future guests. Otherwise, best possible price-quality ratio I can think of.
I have already highly recommended this place to friends and would most definitely come back.
