Great flat - bright, spacious, comfortable, with lots of character. It's in a prime location for visiting sites of historical interest and if you need the metro, it's a 5 min walk (max) away.
Alberto organised transfers to and from the airport for us and was at the property to greet us. During our stay Alberto and Anna were easy to get hold of , available for any queries/requests.
It's a first floor flat just round the corner from the Piazza del Popolo, so there is a constant gentle but pleasant hum from the street. Quiet descends at midnight but you can shut the city out if you prefer by closing the windows and putting the air conditioning on.
Would definitely return for another stay.
