Vittoria Suites is located in the heart of Rome, just two blocks south of the Spanish Steps. You couldn't get any more central if you tried. This is the most beautiful part of Rome: narrow cobblestone alleyways littered with restaurants and shops. All the high end shops are within a block away. The alleyways are blocked off from regular traffic, only taxis and residents can enter, so it's not noisy. Just make sure to arrive in a taxi on foot. We rented a car, which is not convenient for this location. You'll need to park your car in a parking garage nearby, and walk or taxi it to the apartment. There is camera surveillance, so if you drive here, you will get fined, except on Sundays, when driving is permitted.
The apartment itself is perfectly fine. Two bedrooms, a small bathroom, a kitchenette, and a small living room. Adequate for our family of five. Air conditioned, triple glass windows that keeps all noise out, dining table, simple breakfast items included; milk, tea cake, coffee, cereal, crackers, jam, butter. No elevator, it's four flights of stairs. There is a grocery store immediately next door. Federico organized transportation from the airport for us at 65 euros. He was super helpful, explaining where to go and giving recommendations for restaurants etc.
We would definitely recommend staying here. We walked everywhere; Trevi Fountain, Piazza Navona, Campo di Fiori, Trastevere, Colosseum, Forum Romanum etc.
