Absolutely enchanting stay! The location is awesome, right by the city center and close to metro stops and shopping. We had delicious pastries for breakfast every day at a bakery down the street. The house is gorgeous, and has such a fun ambiance. Fer is a fantastic host: everything was spotless, and she and her staff were so helpful and responsive.
Note that since Casa Sauto is right by the square, you may get some street noise, especially on weekend evenings. Just be prepared. Still definitely worth staying here!
