Really great location, we walked to the Coliseum and Roman Forum, to the Vatican City, to the Spanish Steps and everywhere in between.
The apartment was comfortable, with a nearby supermarket, and many coffee shops and restaurants.
Having a washing machine and kitchen was great for us, since Rome was one of many stops in our trip. Shower was great too.
Elevator is pretty old but works for moving luggage up and down. We used the stairs other than during checkin/checkout (three flights).
Overall a great place to stay.
