This listing is literally across from Sagrada Familia. You will have a magical view from the balcony. The neighborhood is very quiet and peaceful as well. Very easy to walk from various cultural sites and museums.
I also got sick with the flu 2 days into my stay (jetlag). Silvia made me some homemade ginger tea and calamari stew. She is very generous and goes out of her way to make you feel like home. This was my first AirBNB experience. Definitely made a new friend in Barcelona
