Alex and Toby's apartment is a great place to stay if you're wanting to experience New York City. We stayed there for 3 months (January-March) with our dog Oscar. We loved that it was a couple of blocks away from Washington Square Park and close to so many amazing, affordable restaurants (Mamoun's, Old Tbilisi, John's Pizza, and La Lanterna were some of our favorites).
Alex was very accommodating in meeting us at the apartment when we arrived, providing a list of accommodations we may need during our stay, and replying to any questions/concerns (our internet went out once).
The apartment itself has a lot of character and has everything you need for a short or extended stay. The biggest drawback is by far the noise. It's on a very busy street, and it can be noisy until 3 or 4am. The white noise machines definitely help, and we eventually got used to it. The advantage of living on a busy street however is that you never know what you'll encounter. For instance one night we returned to the apartment to find Robert Deniro shooting a movie in front of our place. Not only did we get to watch the filming, but because we lived there, we got to be extras! Also because the street and neighborhood are so active, we never felt unsafe walking the dog at night or venturing out alone.
The close proximity to the subway also made exploring other parts of the city very easy. We'll definitely look back with fond memories of our time spent at this apartment in Greenwich Village.
