Ronnie's place is very convenient to the 1 Subway Line and only a few quick stops to get to Columbia University. The room is comfortable and private. You will share a bath with Ronnie and her son, but she is very accommodating to your needs and you'll be able to come and go as you please. There is some minimal street noise from the window in the room, but that is probably quite common in New York City and it snowed one night while I was there so most of that was from plows, not from loud passersby. This is a great value in a prime location on the Upper West Side, and especially convenient for anything near the 1 Subway train (station right around the corner, just a block away).
