Carmen and her fiancee, Harry, are great hosts! Harry scrambled to find us our final Saturday night lodging due to my own stupid mistake when booking the apartment. He went above and beyond to assist us.
The apartment is exactly as pictured in the listing (the photos weren't taken ten years ago), and is very clean. One can walk to all the main tourist sites - Pantheon, Colosseum, Forum, Vatican, Borghese Gardens, Trevi Fountain, Spanish Steps, Vittorio, etc. If you're not a big walker, there's a taxi stand about two blocks away at Piazza San di Pantaleo.
The apartment is located steps away from many wonderful restaurants on Via del Governo Vecchio. People-watching is delightful! Harry also recommended the very near and reasonably-priced Lo Zozzone - delicious white pizzas. Its resident dog, Dora, is also charming. There are many restaurants facing the nearby Piazza Navone, but we found most of them to be overpriced. Although the apartment is close to a relatively busy one-way street, the windows effectively shut out any noise.
All in all, a great choice!
