Rosa is very lovely and a super nice host, she gave me really good tips on what to do and where to go, if you‘re into arts, she‘s the perfect host for you.
The flat is lovely and you could even use the kitchen, although I never did, due to the many options to eat out in NYC.
The area is perfect if you like to stroll around, go shopping in the various vintage shops, eat out or have a drink, i also definitely recommend to rent a bicycle, from greenpoint you can go around brooklyn and also cross over to manhattan quite easily.
