Antonio & Valentina's apartment is an excellent choice for staying in Rome.
The place is just right for two, has all the amenities you need, is very clean and neat, and even has a small kitchen if you prefer to make your meals, although the great food the roman restaurants provide.
The wifi in the apartment worked smoothly.
The location is excellent, since you are a mere 500m walk from Trevi Fountain, 200m from the subway station and every main visiting site is within a 25 minute walk radius.
Valentina was very polite and helpful, and I advise everyone to check out the recommendations she provides, as there are some very nice places to have a good meal.
All in all, Trevi Flat is an excellent choice if you want to stay in the center of Rome and have an easy and chilled out place to stay during your visit.
Thumbs up.
