The room has practically everything - plenty of towels, iron, hair dryer (it only lacks a small kitchen sink...), and snacks, coffee, tea, etc. ... - plus lots of suggestions on things to do.
It has access to 3 subway lines - one of them is an express line to downtown, so it's very convenient.
Overall my first airbnb experience was extremely pleasant - no worries at all. Many thanks to Catherine and John!
