A quick summary: stay here - the apartment has everything you need and I believe is ideally situated. Paolo is the epitome of a superhost.
A bit more detail: Paolo met us at Ostiense train station and gave us a lift to the apartment which is just a short walk away. The area has a lovely vibe and is non touristy and at the same time is within easy reach of anywhere you want to go. The weather was awful but somehow we managed to stay dry and have a great time in Rome. The apartment feels like home and is full of stories and love. Paolo goes above and beyond what is required from a superhost. It’s our third time to Rome and we have stayed in 3 lovely Airbnbs. We are planning to return next year and will stay at Paolo’s apartment if we can.
