I really enjoyed my stay at Christine's apartment, and it was perfect for my needs. The location is great, with easy access to lots of cafes and shops etc, and a short walk to bus and subway stops. Just a 10 min walk to the northern end of Central Park, or 20 mins to the Metropolitan Museum of Art.

I can't comment on the experience of staying in the living room of the flat, as I was lucky enough to have the whole apartment to myself for the duration of my stay, as Christine was away. This meant I could stay in the bedroom. This was a great deal as it meant more space and privacy, just like having my own apartment. But it also meant I didn't get to meet the cat... :-(

Comfy bed, hot shower, fast wifi, access to kitchen facilities, it really ticked all the boxes for me. I'd imagine sharing the apartment would obviously be a bit more cramped/inconvenient, but I don't know how common it is for Christine to be in, or out. I didn't actually meet her at all, but she was very prompt in staying in touch through Airbnb messages, and responding to any queries I had, so it wasn't a problem.

I had a little trouble getting into the flat initially, as Christine was out at work, and coming from overseas I couldn't access the internet to contact her: she had actually left a message explaining how to get the key, so this was just a communication issue - if you know in advance you won't have phone/internet access I would double check arrangements for checking in before you arrive. (The cafe/bakery at the end of the street has free wifi)

Generally the street was quiet, apart from friday and saturday evenings when locals gathered on the street outside to play loud music from their cars and have the occasional domestic dispute. If you're out in the evening it wouldn't be a problem. It's definitely not a rough neighbourhood, but not completely peaceful either.
