Pros: the room is beautiful, large and very clean. The bed is very comfortable. The terrasse is amazing. Location is simply perfect, walking distance of a lot of sights (via Toledo, Archeology Museum, famous pizza places, etc) yet very quiet. Nadia is a very nice person and she answers messages super quickly.
Cons: there was a problem with the shower during our stay. I am sure Nadia will take care of it, but due to bank holidays/weekend, Nadia was not able to fix it while we were there. Also, as described in the ad, you are sharing the apt with Nadia. One night she had guests in her living room and it was not as quiet as I expected...but my expectations may have been wrong there.
