Francesco and Katarina are the best hosts I've ever met. My wife and I found the apartment very clean and modern and exactly like it was on the pictures. Even it was a private room, we had a lot of privacy. We were provided with plenty of nice towels, shampoo, gel, etc. Every morning a table was served with breakfast - espresso, croissants, cheese, juice, fruits, milk, crisps... Francesco saved us from a long standing in line in museums - he booked tickets online on his own credit card because I experienced some trouble with mine. He gave us very good directions and instructions on how to reach different showplaces in Rome and even in Siena and Lucca. Also he recommended a couple of great restaurants to try the traditional Italian food and wine.
The place is in a walking distance from two metro stations and a railway station.
I would definitely stay there next time when I go to Rome. Highly recommend to all travelers.
