We really enjoyed our 5 nights (family of 4 including 2 teenagers) at Cristina's place. She met us at the apartment and took her time going over all the details of the home. She then gave us recommendations on nearby restaurants, using the buses and subway, local attractions, etc. The location of the apartment is great, literally right next to Sagrada Famila, nearby shops, restaurants, grocery stores, etc. She arranged for a taxi to take us to the airport as well. Highly recommend Cristina's place.
