We didn't actually meet Stephanie, but she and her co-host David were a pleasure to deal with. Our flight was late arriving, but David was still there to meet us. We also had a few hiccups during our stay, and they were both consistently responsive and helpful.
The apartment itself is in an older building in the Annex, and it was a bit rougher around the edges than we expected, based on the photos. The bathroom could really use a reno, as there is some peeling paint and discolored tile grouting. Parquet floors are scratched from wear and tear, and there were screws sticking out of the walls in various places where things presumably once hung. That said, the living room is comfy and we slept well on the bed in the main bedroom. No dishwasher or (as of Dec 2017) cable TV - Apple TV & Netflix were available instead.
It served our purposes, as we were in the city over the holidays and only needed a place to sleep located in that neighborhood.
