The best thing about Carol and Iván's apartment is the location. Sol is a great neighborhood, close to everything to do during the day and night. The apartment is a good size (we were two people). It fit us comfortably. The only things to note are that it's on the fourth floor with no elevator and that Sol can be quite noisy at night (since there are bars and restaurants around the apartment which are open late). We had a very good stay and would recommend this apartment.
