Carlos and Julio’s place was clean - as expected - and located near the young and lively barrio Ruzafa. Carlos welcomed us and he was the friendliest host ever: there was a bottle of cava and he also gave us two bottles of water in case we were thirsty after our flight. Even though I speak Spanish, he explained everything in English so my friend could understand everything. After he left, he remained available at all times through Whatsapp in case we had more questions (e.g. about las Fallas).
Highly recommended!
