We loved this flat and the area around it (the Colosseum is right at the end of the street and Monti is a short walk away; also check out the square and obelisk at the other end). Maurizio was there to meet us when we arrived and was very welcoming, had lots of good tips (pay particular attention to his recommendation of Armando al Pantheon, a near-perfect restaurant). The apartment is in a lovely, peaceful building with a courtyard. It is compact but beautifully laid-out, with lots of good books and DVDs. Highly recommended.
