What a great place! Roof top terrace with a magnificent view. Take tram line 2 to subway station Flaminio or bus 280 to Lepanto and you will be in city centre in no time. Mancini bus hub is around the corner and from there, you can go anywhere.
The apartment is great, well equipped kitchen, bathroom and even a washing machine (just in case).
Pay €5 for an espresso at Piazza Navona or just € 1,50 at Bar Duetto downstairs. Have a delicious pizza at Trentino or at La Teverina di Eli&Ale. Don't be a tourist, be a Roman!
