Let's start with the positives: great location in central Ancient Rome and walkable to all of the main attractions. Marco (and his sister Alice) were very good hosts. However, the bathroom and kitchen were fairly disgusting. Mold in the bathroom and very dirty kitchen (sink especially). And worst of all, it smelled the way described above. My husband can't smell so it wasn't a worry to him, but even the smell gave me the heebie jeevies. In general, the apartment (and especially bathroom) is difficult to maneuver due to low/slopes ceilings and tiled stairs/floors/walls. Some rugs may warm the place up- but perhaps there would be concern for potential mold growth areas... I loved the location and friendly hosts but would not stay again. Unless it was massively cleaned.
