The VRBO we're staying at in Barcelona has a rather cool, unique feature The architect, Bonaventura Conill, was a disciple / colleague of Gaudi. When the building went up, it had four stories. Fifteen years later, two more stories were added. The apartment on the sixth floor is (I'm reliably told) the only residence in Barcelona where you can see both Casa Batlló (a spectacular view out the living room window) *and* Sagrada Familia (out the bedroom window) Bonaventura's grandson owns the unit, raised his kids here, and started renting it out after his kids moved out It's quite something https://vrbo.onelink.me/ItNz/3gq1187f
