We really enjoyed our stay in NYC and Laura's place was perfect for what we needed. It's in a great location, within easy reach of Manhattan via the L-train or a lovely walk across the Williamsburg bridge to the lower east side. The coffee shop next door is great as others have said and the supermarket opposite is very well stocked. There are lots of places to explore within Williamsburg for eating and drinking.
The apartment is quite spacious for a one-bed in New York but there isn't a sofa to relax on (though there is seating) and there's nowhere to easily eat. This was fine for us as we spent most of our time out and about. When we were there it was mainly to sleep. The bed was comfortable and the apartment is quiet- we barely heard any sirens etc. There's also a coffee machine and facilities to cook if you wish.
It was VERY hot and humid in NY during our stay but the air con in Laura's apartment kept us cool. It worked perfectly throughout our stay.
The apartment wasn't very clean when we arrived but we followed this up with Laura, who was really quick and helpful in her response.
Overall, we had a great stay!
