Alex and Gemma's apartment is very conveniently located just a few blocks away from La Sagrada Familia, one of Barcelona's most famous and most beautiful attractions. For those who like to walk, it is a very do-able 1.5 mile trek on mostly flat terrain to Park Guell, which should not be missed. We recommend buying tickets for a guided tour of the park, designed by Antonio Gaudi in the last century. Google Park Guell for links to tickets. As for the apartment itself, it was very clean and comfortable, with a spacious bathroom and well-equipped kitchen. My husband and I arrived quite early and Alex met us at the apartment and allowed us to drop off our luggage while the apartment was being cleaned. While we were there, he gave us a thorough explanation of the features and amenities and spent a considerable amount of time showing us where we were on a map and pointing out various transportation options and sites which he recommended. He was readily available during our stay to answer questions and offer assistance. We highly recommend Alex and Gemma's apartment and would be happy to stay there again.
