Apartments is located in the center of city and you can walk to all attractions. You even don't need to use metro. Host was very nice and kind, always reply on our requests. Was ready to meet us later in the night as our plane landed in Rome at 10 pm.
from areas of improvement i would mark that apartament is quite old and when we arrived were dirty. I have allergy and dust was under sofa in living room, on TV, somebody's hairs in the bathroom. If quests pay for final cleaning i would recommend to use professional service who will guaranty clean.
Apartament good for couple, as sofa not really comfortable.
