We stayed in this apartment for a week. Before arriving, we had some doubts about safety in the area, but the place is actually very quiet and safe. Check in and check out were both flexible and easy (smart lock).
The location is superb: very close to supermarkets, restaurants, coffee shops and, mainly, the subway, which made it very easy to get to Manhattan. The only thing is that the L train is undergoing works so there could be 20 minute delays late at night or on weekends (just a matter of patience!!!)
The apartment was very clean and all the beds (including the sofa bed), really comfortable .
We didn't have any kind of issue with noise from the street (I guess we were too tired to hear anything). We did hear our upstairs neighbors arriving, but that was it, nothing that really bothered us.
The kitchen is well stocked: I'd say the only missing thing would be the microwave oven.
The apartment is comfortable (though not new) and very spacious for NYC standards.
The wifi worked well, which was very important for our children (all teens). All in all, we recommend this apartment, which isn't modern, but has everything we may need. Very good value for NYC standards!!!
