Maria Teresa's apartment is gorgeous - the art and furnishings are beautiful yet comfortable, the building was quiet and charming, and the definite highlight is the top-level terrace. We spent most of our time there, enjoying the view with wine, meats and cheeses from Alimentari Pannella Carmela, right around the corner (see Lorenzo, he's fantastic). There is also a great coffee shop there, and within a two-minute walk, a wonderful farmers market on the weekends. Overall, the apartment is in a great location for walking to many of the major sights of central Rome, and exploring nearby neighborhoods.
Carlo was our contact before arrival, and he sent us very clear and thorough instructions, and was perfectly communicative throughout. Rudi was on hand to check us in, and was very helpful and friendly, providing his own recommendations in addition to those provided in the apartment guide. We truly loved our experience here, and would be happy to book again next time we're in Rome.
