We were 3 people staying at Alisa's flat for 4 nights. The apartment is situated in a nice neigborhood. Comparing with Manhatten, Greenpoint is pretty quiet and calm.
The apartment has an artsy vibe which we loved a lot. Alisa has a wonderful taste. You could stare at those many interior details for hours! The smallest room here is the bathroom, however despite its size, it had everything we needed.
Apartment was clean and in good order. Communication with Alisa was nice and easy (although with some small delays, mostly because of the time difference between Riga and NY).
Apart from enjoying view from the roof terrace, you should definitely go for breakfast at "five leaves" and walk around Williamsburg. But just ask Alisa and she will suggest you several places to visit and things to do. If we come back to NY one day, would love to stay in this apartment again!
