We stayed at Luis’s apartment on may 2019.
When arriving we were greeted by a Woman who works with Luis, she explained us about the place and gave us some helpful tips. The clean and well stocked apartment is located next to the Poble Sec metro station on the edge of the gothic neighborhood and from here you can reach every spot in Barcelona.
In addition, we found that from the apartment it is an easy walk to many points of interest in Barcelona.
One down side that we have encountered is that it is situated above the starting point of a bus line that tends to be noisy. We also found that a neighboring bar patrons are noisy at times.
