Elena gives you great instruction via text. I didn’t get to meet her, because she‘s/ was on vacation but everything went well because she described perfectly on how I get to the apartment (which is beautiful by the way), besides she checked in on me if everything is alright. Very friendly and a great place to get to know Barcelona. The sagrada Família is only 5 minutes down the street and the metro L4 is a 2 minutes walk away as well.
I highly recommend you her apartment. Greets from Hamburg, Germany! :)
