Hotel Piccadilly is placed in an area where you need transportation to visit the city center. The metro station is over 500 m away (0.3 miles), but the metro network in Rome does not cover several areas in the city center. There are four or five buses stopping very close to the hotel, but only one (# 87) goes to the city center. I used bus 87, and average wait time in either direction was over 20 minutes, with a maximum of 40 minutes.
The hotel itself was OK, I had a good room with a good bed and bathroom. Insulation from outside noise is far from perfect, I had a room on the 7th floor and still I could hear the traffic noise. The room and bathroom were smallish, furniture were OK, and the bed was comfortable.
Breakfast was OK, with some choices available. less
