Hotel Regno was spectacular centrally located, clean, super pretty with attentive staff. The breakfast was delicious and had plenty of variety. The rooms were spacious, and despite being just steps away from the Trevi Fountain, no noise from the street could be heard. The staff arranged a taxi to take us to the airport, and when we came down to check out, the taxi was already waiting for us. When I return to Italy, I will definitely stay at Hotel Regno again.
