We took the 2-day tour so we got lots of time to explore the more the historical places of Rome. First day was great with a well-organized bus schedules plus a very nice weather. Second day,we had to wait more than 30 minutes in Termini Station to get on the bus. Unluckily the top deck was closed due to rain showers and the audio-guide was out of service. Because of the bad weather and the traffic jam, tourists had to wait more than 15 minutes for the next bus in some bus stops. But overall,we had fun and we were less stressed because of the nice rides we got for the 2 days.
