The apartment was clean, quiet, modern as it was recently renovated, very well located as it is 5 mins by walk from Sagrada Familia. The room is separated from the rest of the apartment by the leaving room and during our stay, Ileana and Anthony, our hosts, never used it so it was really quiet. In addition, they were so discrete that we almost never met them during the 4 days we spent there (just at the arrival and just before leaving). A very good option to stay in Barcelona which is definitely a great city to visit !
