We've chosen Vivian's place because it seemed reasonably close to the JFK airport (cca 1h 10 min using metro - as after reading stories on the internet, we were afraid of the bus). Unfortunately, metro had some stations closed so the trip from the airport took us 3 hours instead (!).. so not too close. Midnight walk from the station also didn't feel safe, but thanks to precise photos, we found the place & got in without any issues. However wouldn't recommend the area.
Place itself is fine, just as described - just the walls are a bit thin (we got woken up by other guests coming back late). Also, no possibility of slightly later check-out (it's 10 am sharp).
