Marta’s little apartment is a gem. Upon arrival we were greeted by Marta and her mother. And they made us feel very welcomed. The apartment was spotless clean and it had everything we needed. Marta answers any messages within the hour if any problems. The place is also safe and located in a good neighborhood. We walked to La Sagrada Familia and there are tons of nice restaurants at walking distance from the apartment. There are busses and taxis that run right in front of the building. We never had a problem finding a taxi or an Uber.
I would definitely stay there again when we go back to Barcelona.
