Very spacious room with an appropriately large TV. Comfortable bed. Somewhat odd lighting ... a desk lamp, a floor lamp in a corner, a light at the front door, and bed lights. The absence of any central light was somewhat of an issue. And the bed lights are not quite in reach for ordinary mortals while in bed. The website and the sticker on the mirror in the bathroom say housekeeping every 2 days. When they didn't show up, I inquired and was told "it's every 3 days." So they either need to live up to their advertising or change it to say every 3 days. Then they tried to come the next day as well. So there seem to be some disconnects with housekeeping.
