This was our first time staying at an AirBnB and we weren't quite sure what to expect but overall it was great and very convenient.
When we arrived, check-in was easy and we were able to access the keys from a lockbox. The apartment was just the right size for what we needed and in walking distance to several restaurants and shops near Vanderbilt.
Only negatives, which are small: the bathroom sink didn't drain while the water was running and there were no outlets in the bathroom (at least we couldn't find any). Also, although we didn't use the fridge, the outside looked like it needed a good wipe-down.
Overall, we were very pleased with our stay at Kate's place and would recommend it.
