COYOROOM is a lovely, well-designed apartment in the friendly neighborhood of Coyoacan, with many bars, coffeeshops and restaurants (also for vegans/vegetarians). The hosts provided clear instructions on entry, so the apartment was easy to find. It's clean, with a well-equipped kitchen and bathroom. The beds (and pillows!) are incredibly comfy.
Perhaps good to know: the staircase is a little hard to ascend with large luggage.
