The flat is just as it was described and we were welcomed warm by our host. Federiko met us on the railway station and took us to the flat by his car.

It is completely equipped with everything.
The location is quite and very convenient for tourists - away from crowd and noise and the same time with a very access to the all POI for tourists in Rome.

From the guest house to the Piaza Venezia you can go by bus H or 8. The journey takes about 25 minutes.
From Piaza Venezia every POI is in distance of 10 minutes by bus.

Connections:
If you're coming by plane to Fiumicino, it is the best to take F1 local train (8 euro ticket) and after 25 minutes to get down to the station Trastevere. Than from there you must take bus 8 or H (1.5 euro ticket) and get down to the station GIANICOLENSE - Ravizza. The journey takes about 5-6 minutes. Than the distance from this station to the guest house is about 250 -300 m.

If you want to spend some money and reach TERMINI station by bus from Fiumicino (4 euro/ticket), than from there you must take bus H. In this case the journey will take about 35 minutes to the same bus station GIANICOLENSE - Ravizza

Verdict:
Perfect location, quiet and and the same time with easy access to the POI, many small shops and few supermarkets around, excellent flat, no need of noisy air condition, absolutely amazing garden and extremely friendly hosts!
