Mary is a phenominal host and is a blast to talk to. The apartment is located in a lovely area nested between the beautiful central park and riverside park, so you'll have access to a great mix of city life and nature. Its also close to the 2 and 3 lines, which is great for commuting around the city.
However, the apartment can be rather loud being right off a major avenue, so it might not be the best fit if you are a light sleeper (or bring earplugs!). Also, the internet can be rather spotty at times, so it might not be the best for a wfh setup, although Mary will do the best she can to help out!
But would still recommend, especially if you want a unique taste of the uws.
