We've spent 4 days in José's place and everything was great. José is a very nice and helpful person, he offered us some tips and presented the town a little when we arrived. The apartment is situated at walking distance from Sagrada Familia right next to an ex bullfighting arena that's now an event space and it also houses a small museum.
The room itself was not very big but it was everything that we needed for our stay.
We really recommend staying here as you won't regret it.
