What a lovely flat and very much as described. Filippo has thought of everything that you need for a short stay. He was very quick to respond to our texts when we arrived late at night and when we needed help with the wifi. He told us all the areas we would be able to walk to, which were a lot; as the flat is very central for a large number of the tourist attractions with the Colosseum being about 10 minutes away!
The area around the flat is very safe and quiet; it has lots of small unique shops and restaurants/bars very nearby. Go down hill to the end of the street, turn left, walk a short distance and you reach the Cavour Metro stop. The Termini station is a 20 minute walk which is handy for the train and the bus stops out to the airports on Via Giovanni Giolitti.
We would thoroughly recommend staying here.
