Luigi is a great host! He answers quickly to messages and was very welcoming when we arrived in Rome. We also met his father when we left the flat, he was very nice as well.
The apartment is very well located, we were able to do almost everything by foot, the bus station to the airport is on the same street which is perfect and the metro station not too far away. The neighborhood is calm and there aren't many tourists in those streets - we felt like real Romans in the apartment!
Everything was very clean and functional.
I would definitely recommend Casa Winkler!
