We arrived as planned around midnight. Chiara had specified that her friend Marco would be waiting for us and that we should send him a text when we leave the airport. Sure enough, Marco was waiting and showed us to the apartment, which is situated in a very beautiful and old staircase. The lift, is old, and cool and does what it should.
The apartment itself is very nice and cozy. You've everything you need should you wish to cook meals. The bathroom is roomy and clean. The bedroom is graced by a very comfortable and big bed. Plenty of storage space. All house cleaning and fixing things you can think of. Even has a washing machine! We stayed almost a week so we needed this, fan-tastic. So the place, the place is awesome.
The neighbourhood is quiet. There is a large supermarket straight across the street. There are a few cafes just down the street, an ice cream place and a few restaurants just down the other side of the street. It's not the most central of places, but a short walk will get you to San Giovanni Metro A station, from which you can easily get anywhere you want. A tip is to get a daily metro pass. They can be purchased for 1, 2, 3 days etc. From SG you can get to the main train station or a short walks away from say, Trevi Fountain, or St Peter's Square and Basilica/Sistine chapel in the Vatican. All at your fingertips. The area around the San Giovanni station has some quieter shopping and cafe/restaurants as well. This is very welcome after a few days in August in Rome. Tons and tons of tourists.

We didn't have any real contact with Chiara more than to say that we've arrived and were welcomed and that everything works fine. Until we left the place, came to our hotel in Pomezia just outside Rome and realized that our passports are in a drawer in the apartment!!! But a quick call to Chiara solved this and 3 hours later I found her waiting for me near the aforementioned San Giovanni station with our missing stuff. Extremely helpful! This was in the middle of the day on a Friday mind you!!

If you're going to Rome and need an affordable and very nice place to stay at a nice location just pick this. Just do!
