We stayed at Chao's apartment for 10 days. Overall it was a good experience. The pictures and the description of the accomodation are accurate. The private bathroom is a HUGE plus and we loved it! We only saw the host at the arrival and the departure but he was really responsive through text messages. Frank the cat is indeed very friendly, clean and cute and loves to cuddle :) The neighbourhood is ok, though in the late hours can get a little scary.

Only two things that bothered us a little: the cat wants to be in your room all the time, even jumps on the bed and on the table. Of course you can direct it out but that usually results in loud meow-ing and scraching on the door that is particularly annoying at 6 AM.
The other thing is the distance. 15 minutes walking distance to the A/C Train Station and then additional 20-30 minutes to Manhattan (it depends on which part you want to visit). So the distance is definitely something to think about.
