My partner and I were met by Paola's lovely cousin at the apartment upon arrival; she stayed with us for an hour to show all the best places and restaurants to go to on a map that she provided for us. There are many great restaurants, that are open till very late, within a 5 minute walk of the apartment and also 3 supermarkets nearby to stock up on any essentials that we needed.
The apartment had everything we needed and more: towels, hairdryer, iron, washing machine etc. There is an adjacent apartment (used by other guests if you only have a small party) - but they do not have access to your apartment if you lock the second door behind you. Our side of the apartment was lovely and clean and it is only a 30-40 minute walk from the Colosseum, Trevi fountain and Spanish Steps. It's located between the two Rome train stations and a 10 minute walk from the Metro line which makes everything easily accessible.
Paola organised a private taxi to take us to the airport on our last day and we didn't have any problems that required us to contact her during our stay.
Good location, great food and a lovely apartment!
