I would recommend Carlo's Airbnb for short stays. The kitchen has everything I needed to prepare quick meals. Carlo is not only a pleasant host, but also very clean. Being coealic, this was a great added value :) The Airbnb is 5 min walking distance from Plaça d'Espagna and Santo Domingo metro stops. Being a woman, I never felt unconfortable sharing the apartment with a man. Carlo is very respectful and polite. I recommend his Airbnb to those women who might feel a bit hesitant with the format :)
