We loved staying at Sara's place. It was conveniently located - there were 2 nearby Metro Stations and La Rambla and Gothic Quarter were walking distance. There were restaurants and supermarkets just around the corner.
Sara and her daughter were very helpful too. There were milk, water and soda in the refrigerator. They allowed us to leave our bags before check-in. They gave us turrons to try. They also help us get a taxi to the airport.
Our stay in Barcelona was wonderful thanks to Sara, Ollala and Ignacio.
