The apartment is located in the Gracia, a neighborhood with narrow streets and lots and lots of little shops and small restaurants.
It's about 20-30 minutes of walking toward Sagrada & Parc Guell.
Jordi was very helpful, he provided us with a map and recommendations for things to visit or do.
He even arranged for a taxi to pick us up from the apartment when we left.
Great experience, I hope I'll be back soon.
