We absolutely loved Gemma and Alex's apartment. It is in a nice quiet area away from all the tourist spots. It is a short walk to the metro and Park Guell. From the small balcony you can see the top of Sagrada Familia and the sea. It was a perfect fit for my husband, two daughters (1, 3) and myself. We did not meet Gemma or Alex. Alex's sister met us at the apartment upon arrival and was more than helpful. She toured the apartment and ran through a nicely put together binder of the different areas of Barcelona. She even arranged for a taxi to pick us up for our departing flight. I would recommend this apartment to anyone visiting Barcelona.
