My wife and I stayed at Stefano's apartment for 3 nights to celebrate our 10th anniversary and it was amazing!

When I first contacted Stefano he was extremely responsive and answered all my questions.

Due to late arrival (Literally in the middle of night), Stefano insured me it is not a problem and arranged a car for us to pick us up from airport straight to the aprtment there at 2 am we met him and Valeria. He helped us with the luggage, and showed us to the apartment, reviewing the amenities, and getting insights on what to see where to dine with lots of patience.

Regarding the apartment, LOCATION, LOCATION, LOCATION. Just couple of steps you are at the Pantheon, just the center of Rome, from there we just walked to all the sightseeing, Campo de' Fiori, Piazza Navona, Colosseum, Spanish Steps, Trevi Fountain, Vatican Museum and so on, no need for taxi or metro, it is just that close to everything.
The apartment has fully equipped kitchen, but hey, you are in Rome, who wants to cook? We ate outside following Stefano's recommendations.

Wi-Fi worked great, Air Condition worked great, Hot water, everything was clean.

If staying in Rome, I can't think of a better place then here, I would definitely stay here again.
