Tania is the nicest host I've ever had since using Airbnb. She makes you feel so welcome into her home; she offered us snacks, drinks and dinner the night we arrived, and chatted to us whenever we bumped into one another. Her communication with us was fantastic! On the last night, Tania cooked us dinner and we drank and danced with her, making for a wonderful night.
Her home is absolutely gorgeous; it's so unique and colourful, exactly as advertised (although it's even more amazing in person!)
Her house is a 5 min (maximum) walk from Torre Gaia metro station, which has links into the city centre. Whilst it is quite far out from the centre, the transport links and close enough and quick enough to make Tania's place a great stay if you're wanting to visit Rome.
Could honestly not recommend Tania and her home more; my time at her airbnb was splendid.
