The apartment: it corresponded to the description and had exactly what we had hoped for and which is not so easy to find in NY: a spacious living room with views of the Manhattan skyline, a cosy bedroom and a kitchen where you can actually cook if you feel like (we did). And it was the cleanest apartment we have booked by Airbnb so far. Additionally, the supply with towels, shampoo, soap etc. was exeptional and after our long journey we were especially happy about drinks and snacks we found in the fridge provided by our host. The heating is a bit noisy, but was perfectly adequate during our visit in March / April. Tip: In case of heavy rain (twice during our stay), the windows can be leaky, so it is a good idea to put a towel on the ledge to catch the moisture.
Location: no noise from the street or else. Very good for relaxation after sightseeing: the couch. Greenpoint is definitely in transition and this made it very inspiring for us. In before, we did not know it was once a Polish-American immigrant community, but this made it even more interesting.
Infrastructure: it is only a few minutes walk to the nearest subway station (Greenpoint Ave, G line) and with one change you are already in Manhattan. Both airports we used for arrival and departure (JFK and Newark) were easy to get to by subway / train, despite our suitcases. Supermarket, wine shop, bakery and laundry are within walking distance. Tip: On Saturdays a short walk will take you to the East River State Park (90 Kent Ave) and the open-air food market 'Smorgasburg' (NY Times: the Woodstock of Eating), which you definitely should pay a visit (and be it only to catch a bite of the popular 'Ramen Burger').
