I highly recommend Valerio's apartment. It is large (for up to 4 to 6 people), very clean, comfortably and beautifully furnished with fine furniture and artwork, and well located--a short walk to Coliseum. 2 bathrooms provided comfort and privacy. With four people showering every morning we had no problem with hot water. It has an elevator and a very pleasant courtyard with plantings. Unlike another reviewer, we were not bothered by any sirens. There is a bus stop outside, but we got around by walking or taxiing. If you are near the apartment for lunch, I recommend Osteria Taralluci e Vino just down the block. It is frequented more by locals than tourists. Valerio was out of the country when we were there, but that did not prevent him from being available through WhatsApp. We would stay there the next time we visit Rome.
