We truly loved visiting Rome and a large part of our satisfaction was due to our wonderful experience staying at the New Apartment Sistina-Trevi! Delia, our hostess, could not have been more gracious or welcoming. She is truly a gem. She went above and beyond to make sure that our needs were met, thoughtfully stocking the apartment with juice, milk, wine, fruit, yogurt and other snacks so that we did not have to shop immediately upon arrival and even providing shampoo and other toiletries, laundry detergent, etc. She emailed with us frequently both before, during and even after our stay to make sure we had everything we could possibly want or need, offer advice and information, and ensure that we were comfortable. At one point I suggested that an American coffee maker would be good to have in addition to the fancy Expresso maker that she had already provided, and 20 minutes later she knocked on the door and presented us with a newly purchased one- which we happily used throughout the remained of our stay (thank you, Delia!!) She answered all of our questions, provided restaurant and travel recommendations, and booked a taxi for our airport departure on our last day. Despite the fact that she speaks no English and we don't speak Italian, we communicated effectively (sometimes a bit hilariously) through google translator and the Air BNB website translator and all went very smoothly.
The apartment itself, located in a charming old Roman building on a picturesque small street in a convenient and central location, is highly recommended. It is spacious and comfortable as well as airy, spotless and attractive. It had everything needed and more for our family of three, including two comfortable bedrooms, two beautiful and spotless bathrooms (one shower), a washer for laundry, an eat-in fully equipped kitchen plus a large dining table in the living/dining room, good internet service, excellent air conditioning -- and was mercifully, QUIET in the middle of Rome as it faces a landscaped garden rather than the street. These qualities were much enjoyed, as we frequently returned during the day to rest or freshen up before heading out again in the evening. There is a tiny elevator, very useful for luggage or tired feet after a long day, or one can easily walk up (only 2 short flights). The location is fabulous, within walking distance of many restaurants, shops, and most of the major tourist sites. For longer trips there is a subway station on the corner and a taxi stand about 1.5 blocks away -- very convenient as getting a taxi in Rome on the street is not a given. (There were buses, too, but we didn't use them).
Overall this apartment more than met our needs in every way and we would recommend it, and Delia, very highly!
