This apartment was perfect for our 7-day stay in New York. There was ample storage and shelving for all our clothes, a table & chairs for breakfast. The kitchen unit was good to have, but we ate out most of the time. The toilet/shower room was nice and clean and the shower had good pressure. We did notice some dust under the bed and since it is designed to fold away, we had expected that to be cleaned. Occasionally, the AC unit on the roof can be quite noisy at night (especially if you're used to a queit room). We were so tired from our day's activities that we could sleep through, although I recommend earplugs just in-case.
Harlem is an intereseting area, it's a side to NYC you'd never experience if you stayed in Midtown. It feels like a safe area, although it's important to stay alert and aware of your surroundings (as it is in all of NYC). The subway station is only a couple of blocks north which was really convenient. Takes about 20 minutes to travel downtown. Highly reccommend buying a 7-day subway pass for $33. We used the subway several times a day, Manhatten is huge! We even took public transport back to JFK upon leaving at 2am! (135st st. Subway 2 or 3 to Penn St. Station (inc. in 7-day pass $33)-> LIRR to Jamaica ($7.50)-> AirTrain to JFK ($8) Total around 1 hour 45 mins. I think an Uber was around $70-80.
