Our stay at Sergi's apartment was amazing. He was a wonderful host and was very helpful and responsive.
The apartment itself was clean, spacious for 4 people and exactly as it appeared in the pictures. It is in a central location in Barcelona and within walking distance ( 2-3 city blocks) to the metro. There is a grocery store right up the street, and a convenience store directly downstairs. La Sagrada Familia is also within walking distance (15-20 mins).
Enjoyed my stay here and will definitely recommend!
