The apartment was in an ideal location half way between the Pantheon and Piazza Navonna. Quite roomy and the air conditioning was a god send as it was quite warm when we visited.
Marco was an excellent host who greeted us at the door and insisted on carrying our heavy suitcases up to the apartment. His suggestions for restaurants was great (there is an excellent restaurant 20 feet from his door).
Would stay there any time I am in Rome.
