Unfortunately I didn't get to meet Juan, as I was told I'm advance. But his friend Rosario was there to meet us upon arrival. She showed us around and was extremely nice and helpful. Juan even called a few hours later to make sure everything was ok and texted tons of recommendations for places to eat and things to do.
The apt was exactly as listed. There is no air conditioning, but it honestly wasn't needed. The widows were open and the fan was sufficient. 15 mins or something walk to the beach. And another 15-20 mins walk to Sagrada Familia. For the most part we walked everywhere or caught a taxi. Would highly recommend this place to anyone. It was a quiet neighborhood and not full of tourists also.
