Kay's listing is extremely conveniently located in north west DC, especially in our case since we were attending a conference at the convention center nearby. There are a few unmanned parking lots next to the location that were great to leave our car in for our stay there. The neighbourhood felt safe and comfortable; there are plenty of restaurants and bars within a 15 minute walk from the place. The house itself matches the photos - I will note that the bedroom has no windows and is therefore very dark in the morning.
The wi-fi in the house was a major problem for us - it completely cut out 5-10 minutes into any video call we took. It also cut out if more than one device in the house was streaming video. This made working from the house impossible because we had no idea when the wi-fi would come back online. To make matters worse, when we contacted Kay about this issue we got no reply at all. In fact there was no communication from Kay after we were given check-in instructions.
