Etan was wonderful host with great communication prior to my trip! Very clean and nice apartment. It is walking distance to Columbia's medical center which is what I was looking for! There is something going on with one of the pipes in the room- so it will frequently make a loud noise during the night (lasts <1 min). Etan is aware and has a white noise machine in there to help, but I would recommend ear plugs too (with the ear plugs I was still woken by the noise). I stayed 1 night and it wasn't a problem for me because I could easily fall back asleep, but something to keep in mind if you're planning a longer trip!
