Overall really nice apartment. A lot of light and space. The bed is big and comfy. The apartment has all all the essentials - large TV, good WiFi, decent shower and equipped kitchen for eating (not sure about cooking, since we didn't really cook).
The lock isn't the best and sometimes the key gets stuck. However, once we explained that to our host she got us a new key within 15 minutes, and it worked much better, so really not much trouble there.
The apartment had a small soap and a few towels when we checked in. Not sure what the standard is, but it would have been nice to get a bit more stuff, like shampoo and body soup.
Location was good for us since we visited some family members that live in the same block, but if you're interested in Manhattan it's about 5-10 minutes to walk to the subway and then about 15 minutes to downtown. The area of the apartment is really nice though and full of place to eat and drink.
The host left some instructions and tips on a paper in the apartment, which was nice to have. The instructions did require us to wash the dishes and take out the trash when we checked out. It wasn't much trouble for us since we didn't really have much dishes, but it's something to take into account if you don't really want to clean during your vacation.
Overall can really recommend this apartment, it's nice and comfy and the host is really responsive and helpful. Great place if you're looking to stay in Brooklyn!
