It’s a little tricky to find and best to call Ma Elena once you see Cafe Avellanada. She will let you drop off bags if need be, but no bathroom use until you get your room. This is a little guest room on her private property and is located very close to everywhere you would want to go in Coyoacan. I walked everywhere and felt fine as a solo female traveler in the evenings in this neighborhood. My room was clean and had anything essential that was needed This is a no frills, wonderfully located, inexpensive room!
