The apartment is very bright, clean and exactly what it looks like on the pictures and what it said in the description. It was even better than expected and had everything we needed and more. We stayed for 4 days.
There is a bus stop, a train station, supermarket, food places and everything else you need just around the corner.
We mostly walked into the city and back to see more of it and it was perfectly fine (30min if you have a good pace)
Cristina and her mother are very friendly, professional and enormously quick to reply to any message and gave great advice and support.
I can only recommend to stay here if you are in Rome.
