I'll start with: I would not stay here again, or recommend for any long stay. I stayed with a friend in the Fauna room. We are both larger sized women with hips and not in athletic shape.
PROS: The location is amazing. The price is affordable. Antonio who works in the morning was very nice even though he doesn't speak fluent English, he works hard and does his best to host and help. He was wonderful.
CONS: Bed: like sleeping on a futon, very hard, thin mattress. Pillows were flat and firm. Bathroom: Shower is capsule stand up like on a cruise ship. Very difficult to maneuver around in. One morning the water fully cut off. Room in general: the rock walls while pretty, are FULL of dust. Room is dimly lit. I didn't notice until packing up that the wall with area to hang your clothes looks like it is full of mold growth? I believe between the dust and possible mold that is what caused my constant allergies in the hotel. Both my friend and I were sneezing often while in the hotel but ok when we left.
Yes the stairs were difficult but it is common in Europe. This is my 7th visit to Europe, 20 hotels, by far the least cleanliness.
Breakfast was extremely basic, again though for the price ok, IF it was CLEAN and maintained properly.
