I did not have the opportunity to meet Lilian, but regarding the apartment, I could say that it was as described. The room was spacious and very clean, and the apartment in general as well. All facilities were very well maintained and you have everything available.
The apartment was very close to bus and tram stops, but if you want to walk, it is a bit far from the Colosseum.
Finally, it is important to mention that you should read the instructions before arriving at the apartment so as not to have any problems at check-in.
