We were absolutely blown away by the apartment and by Enric's hospitality. If possible, it is better than the ad purports it to be. Perfectly appointed with everything you could possibly need, we found ourselves not wanting to leave and spent tons of time just drinking wine on the balcony and admiring the cathedral. I couldn't recommend Enric and this place more and we will absolutely be back.
From a sightseeing perspective, we really benefited from buying a multi-day metro pass, as the metro is right outside the front doors of the apartment. We were able to go everywhere so efficiently. We also did the hop-on hop-off bus and loved it. It also has a stop just across the street from the apartment. We of course did the Sagrada Familia tour WITH tower visit (highly recommend). Definitely do not miss going inside the cathedral.
We are filled with gratitude to have found this apartment and will never forget our experience with our family there!
