The apartment is in excellent location to all tourist areas to hit. My fiancé and I are not walkers but we were able to walk everywhere.
But there were issues. Before we left for Barcelona I contacted Luis to ask which is best way to go to the apartment from the airport. He directed me straight to taxi when there was a subway option. The subway is great in Barcelona and very reasonably priced. He did not want to be bothered.
Also, the air conditioner did not work and leaked water. We went in July when it was hot. Sleeping conditions were rough since it was so hot. We went downstairs and asked for it to be fixed but no one ever came.
