The suite is exactly as pictured and includes a literal washcloset, a small closet with a mirror, towels, outlet and sink (I noted the outlet but did not use, may not be active). The WC was way more useful than I would have thought, considering the shared bathroom the WC was great for getting cleaned up and ready while we took turns showering. No AC in the house but we visited in July (2017) and with the screens over the windows and fans that Cynthia gave us we were perfectly comfortable (and we know heat, we're from South Florida).
For our own trip we decided to rent a car and I'd only note that the street parking in the neighborhood is limited, ask for a compact and settle in with your parallel parking skills. A few nights we could only get a spot a few blocks away but 3-4 blocks in the neighborhood is not a bad walk at all, even with luggage.
We had everything we needed to make coffee in the morning. We arrived late in the evening on a Friday and Cynthia kept in contact with me the day of, even before I got on my plane, to coordinate our arrival. She took a good amount of time to orient us and thought of everything we could possibly need. Keep in mind that when you stay here you truly are a guest in someone else's home, Cynthia is extremely welcoming and communicative but be considerate of the shared spaces. Would 100% stay again.
