We had a great stay at Esther's apartment! The views from the terrace are gorgeous, and we found the rest of the apartment very unique and charming.
The location is perfect and you can walk to almost all of the destinations in the city, especially the Barri Gótic and Ciutat Vella. (Sagrada Familia = 30-minute walk, Beach = 20-minute walk, Casa Batlló = 15-minute walk, etc.) We barely used the metro at all!
Check-in was really easy, and Esther was quick to respond throughout. There are a lot of stairs as the listing mentions (about five flights), but we didn't mind the walk. The views made it worth it!
Gracias por todo, Esther! Nos vemos!
