We stayed at Jordi's apartment on two occasions during our week trip to Barcelona and it became our little home away from home.
The apartment was super clean, and came as pictured with an amazing balcony. Communication from Jordi and Ana was great and they were super accommodating to our needs.
Apartment is very centrally located, in a very walkable part of the city. Plenty of great restaurants around within one or two minutes walk, with a convenience store located right next to the entrance.
Check-in was super easy, though data access is required on your phone.
