I cannot review Cathy's place highly enough. It is an incredible value for anyone looking to stay in NYC - shortterm or longterm. I stayed at Cathy's place for one month while doing an internship in lower Manhattan. The location is excellent - just a 2 minutes walk from the R/F/G lines, and very close to other lines as well.
As far as cleanliness and amenities, the place is absolutely spotless and contains all that you could want (a coffee maker, tea kettle, private bathroom, towels, private entrance, television, wireless and so on). Laundry is not included, but there is a laundromat very nearby which is really nice.
What really made the stay perfect to me was all of Cathy's thoughtful touches and preparations for my stay. From paper towels to tea to washclothes, there was everything that I could have needed and even more, which really made me comfortable and made my stay even more enjoyable.
For those who are considering a longer stay and are concerned about the kitchenette, I found that it worked really well for me for a month, and I am someone who likes to cook. There is a toaster oven, microwave, and relatively sizeable fridge, and towards the end of my stay, Cathy ended up purchasing a hot plate with pots and utensils etc so there is even is a place to cook more now as if on a stove top. It really was no problem at all and I felt like I always had everything I needed!
Communication with Cathy and her partner was excellent, and again overall I just don't think you could get a better value anywhere. The space would be an ideal place to stay in any city, but especially in NYC! I highly, highly recommend it!
