Montse was very accommodate throughout my trip to Barcelona. She provided clear information on how to get to her place and where to visit. I stayed for 5 days and enjoyed that it was close to where I needed to go. As many reviewers have mentioned, it is only a 10 minute walk to the Sagrada Familia, and less to the Verdaguer metro station. Lots of taxis pass through Carrer de Arago and you won't have difficulty should you need one.
