My host, Crystal, made me feel welcome by being super-responsive. I contacted her only a few days before the date I needed to arrive, when Crystal happened to be on a business trip in Europe. Even though she was out of the country, she wrote from Germany that she'd arrange for her housekeeper to get my room cleaned and ready for me to use, which she did. When I had a minor problem with the key, the building staff helped me with it. At the time I texted Crystal about the key problem, she was on a flight from London to JFK and she replied as soon as her plane landed and agreed to add information about how to use the key to her listing. I had an opportunity to meet Crystal at the beginning of my stay and I had a comfortable stay in her apartment. Her view across the Hudson is even more spectacular than it looks in her listing photo. I've already booked a return visit next month.
