We really enjoyed the stay. The local was unbeatable. We walked everywhere during the 2-week stay. By foot, the apartment was 25 min from the Vatican City, 25 min from the Colosseum, 15-min from the Pantheon, 20-min from the Trevi fountain, and 20-min from the Spanish steps. Every evening, it was a short 5-10 min walk into Trastevere for dinner and gelato.
The apartment was clean, and all the appliances worked as expected.
The small downside was the noise level. The plaza below was filled with outdoor diners until past 11PM every night. Weekends were a bit noisier as people stayed out longer. However, it really wasn't a problem for any of us.
Overall, we really enjoyed staying here and would highly recommend the apartment to our friends and family.
