Luis has a beautiful apartment two blocks away from la Sagrada Famiglia. The two bedrooms were perfect for my wife and me and our 16 year old daughter. The apartment has good hanging out space, and a huge patio with a great view of the Cathedral. It is a long walk or quick Uber to Las Ramblas and the Gothic Quarter, but the location was perfect for us.
Luis is an excellent host - he was flexible with our scheduling and spent a long time with us when we arrived showing us the apartment and talking about Barcelona with us. He helped to make our experience even better.
