Lakisha's place is great, with just enough room to sleep and recover after trips around the city throughout the day. It also fits an air mattress at your request, but I recommend sharing the bed if possible. The air mattress will cramp the room and makes it difficult to use the closet.
Lakisha also left some light toiletries for us whenever we arrived and was beyond helpful with our requests, like when we asked for fresh towels after a few days into the stay. Overall, communication is one of the best things about staying on Lakisha's property, as a response is never too far away.
I'm not sure if the other people on the floor are other guests or permanent tenants, but keep in mind that the floor's bathroom will be shared with them. After a day or two, or if you get up early enough, you can can learn when is best to dip into the bathroom to shower and get ready in the morning. But being speedy is still a good skill to have as I'm sure no one enjoys making someone else wait on you in order to use the bathroom.
The wi-fi signal could be a bit weak/slow/inoperative in the room, but overall was solid enough for light browsing. I didn't personally do much Netflix streaming or anything but my traveling companion did and she was fine.
I'm no NYC native, but the unit was a short walk to nearby subway lines, including the L toward Manhattan. Most of our trips to the island were a 45+ minute trip with subway rides, so keep that in mind. Navigating Brooklyn by subway was about the same for our purposes, so maybe be ready to Uber if you want to navigate the outer boroughs a bit faster.
In the end, Lakisha's place is a solid visit if you're looking to stay deeper in Brooklyn on the cheaper end of the budget, but also remain decently close to Manhattan and the other neighborhoods closer to the island. While we didn't have the chance to personally meet, her communication was amazing: swift, warm and kind. Would recommend.
