We loved staying here for our short trip to Barcelona!
Rosanna was communicative and gave us clear instructions for how to get to the flat. Pepe welcomed us into the flat when we arrived, and was *extremely* thorough in showing us around the apartment as well as explaining the map of the city and things to do while we're here.
It was great having two bathrooms, and sleeping arrangements were very spacious/comfy. The entire apartment was spotless, modern, and beautiful.
There's a coffee/cupcake shop next door, and we were surprised by how walkable the location was to some of Gaudí's buildings, nice restaurants, and transit.
I would definitely recommend staying here :)
