A wonderful apartment for a large group in a great location in Rome. We were two families, totalling 8 people, and we had a room to spare! The kitchen is well stocked (and even has a little balcony) and the living room/dining area was a great size, with a table that easily fit 8 people.
We stayed in July, and it was hot! The aircon was decent though, and there were fans in every room as well - between the two, we were cool enough.
Marta was a fantastic host, with great communication beforehand, and during our stay. She replied all messages, whatever the time, promptly.
Location wise, we were able to walk to all the main sights in Rome, with the exception of the Vatican, but the apartment is close to the train station and bus stops as well.
I really don't have anything negative to say about this apartment - it is a fantastic place to stay if you are a larger group exploring Rome!
