Five of us total stayed one night at Eduardo's accommodation. The accommodation was very easy to get to from the airport as it is conveniently located near Placa de Catalunya, which is a hub for metros. There a slight issue with being able to get into the accommodation but it was quickly resolved by contacting the number provided by Eduardo. Also, the accommodation is a short walk to La Rambla and only a 20-30 minute metro to La Sagrada Familia or Camp Nou. Definitely recommend staying here if you are looking for a conveniently located accommodation in Barcelona.
