I stayed for a month and and spent more time out than in - as I imagine most NYC visitors will want to do - and it went very well.
Sasha herself is a warm, friendly host who knows the neighborhood well. We communicated by app before the stay and set up plans which worked out great.
The location itself really is ridiculously good. There is an HMart across the street with good restaurants like Ippudo Ramen, Tim Ho Wan, The Smith, Yellow Rose, and Bites of Xi'an less than five minutes away. There is also a wash and fold laundry service across the street and subway stops 1-2 blocks away. Union Square and the NYU Stern campus are a little further away but still an easy walk.
Now for conditionals: There are pets in this space so those who can't stand cats/dogs will have a harder time. Your mileage may vary on the cleanliness as well - a natural consequence of having pets.
Overall, I enjoyed my stay and the great company.
