Lidia's place is in a great location in the middle of El Born, very close to the metro. Close to all the activities without it being touristy.
Our space was on the other end of the apartment from hers (closest to the bathroom) so there was no problem sharing the space. Also very sound proof. You had you own lounging area with doors that closed.
The room in the loft was just what we needed to come back to after a long day, albiet low ceilings (around 6'1).
