We had a lovely stay at Carlota's apartment. We slept great in the bed, had nice mornings and evenings on the terrace, the bathroom was very clean... No complaints! The church is right in front of the terrace, but the bells didn't bother us at all.
The neighbourhood was very cosy and lively with families, kids, seniors... We felt like locals! We recommend eating tapas at Rabbar on Plaça de la Concordia. And for brunch there's a nice place 5 minutes away, called Oh Mommy!
There were a lot of options for public transport, with the L3 metro taking you everywhere you want.
We would definitely book this place again!
