This was our first time using airbnb, so we were a bit unsure of staying in a privately let room. However, as we didn't want to spend hundreds of pounds on a hotel room that we would only be in to sleep (there's just so much to be done in NYC!!), airbnb seemed the logical choice.
Unfortunately, we didn't get to meet Sylwia during our stay, but she had left the room ready for us (with clean sheets, towels and a hairdryer), and we stayed in contact with her over the 6 days. The room itself is on the ground floor (I think in the US they refer to the ground floor as the "first floor") - as soon as you enter the building, the door is on the right. It was comfortable, and big enough for 2 people and luggage - there's a bedside table with lamp, desk with chair, clothes rail with plenty of hangers and storage space as well as the ensuite (shower, basin and wc). The building is a 15-20 min walk from Grove Street Path station. Wrap up warm if it is cold (gloves hat and scarf are essentials for this time of the year). There are plenty of food establishments as well as bars/pubs nearby - many open into the small hours. The local area is very safe - we would head off into Manhattan (33rd Street - a couple of blocks away from the Empire State Building in midtown - is a 15 min ride on the Path) every morning around 8am, returning close to midnight.
I definitely recommend this location for anyone going to New York. You get the quiet of a New Jersey suburb, experience the commute on the Path and when you walk up the steps to streetlevel in Manhattan, the hustle and bustle of "the city that never sleeps" hits you in the face. This was my wife's first trip and she loved it - we would definitely consider Sylwia's place again in the future.
Tips - work out how many times you will use the Path and subway - you can save money buying a 7 day unlimited ticket which saves you having to reload your metrocard. Try to grab a bite on the run during the day (plenty of stands all over the city - and hot dogs aren't the only things they offer), then choose a restaurant locally for dinner - avoid eating in the theater district/near Times Square as the prices are much higher. US portions are bigger than in the UK, so one big meal per day is more than enough!!
