The house was absolutely okay and the instructions on how to get the key were clear. We didn't really use the common areas such as kitchen and living/ dining room since we always went into Manhattan every day. The room was clean and although the beds squeaked a lot, they were quite comfortable. A lot of other guests noted the shady neighborhood and feeling unsafe walking back to the apartment late at night. My friend and I never had any trouble with any shady people nor did we feel unsafe around the neighborhood as we walked back from the Light Rail station.
The host always replied quickly if we had any questions about check in, etc. Even though Check out is at 12, Sylwia/Magda allowed me to stay longer in the common areas since my flight didn't leave until the evening. Which was very nice of her.
For the price this accommodation is absolutely recommendable and okay. We always took the Light Rail from Liberty State Park to Exchange Place and then the PATH to WTC which took about 30-40 in total (including walking to stations).
