This apartment is perfect. It was very clean, comfortable and spacious for two people. The apartment is steps away from several restaurants and gelato, not to mention the Colosseum is right there! It is easy walking distance to the Pantheon area, though we did take a taxi to Vatican City (there is a taxi stand very close to the apartment).
Andrea was very helpful, giving us tips and advice. He even booked a private taxi to take us to the airport. I would definitely stay here again if I ever find myself in Rome.
