As good as it says on paper. Buses available regularly. There was an option of having a roof on the top floor bus and one without. Sights information and history available with free earphones. Lovely service.

The OMNIA card was great and easy to use. It gave us skip-the-line access to all the Vatican attractions plus Colosseum and Roman Forum, not to mention the public transit and hop-on hop-off bus! Definitely something to look into if you want to see all the Roman and Vatican sites without having to do multiple bookings on various websites.

On first bus the trip was nice, until we had to change to a different bus for a medical reason, apparently no air conditioning in the lower section, and yes extremely hot down there. No surprise some needed aid. In the second day we sat below with one that had air conditioning, very nice, later that day sad in one with no air, not nice at all when its 32c outside. The audio is nice, but miss aliened when driving through the streets and attractions. Overall not to bad.

Really enjoyed the hop on hop off would definitely recommend we were in Rome for 3days we arrived lunch time and took the bus just after 3in the afternoon, we actually got to us the bus for 3 days as the ticket did not run out until just before 3 on the 3rd day brilliant!

A few things to know about this service: 1. The "Vatican" bus stop is 20 minute walk from the Vatican (across the river). 2. There are dozens of haukers trying to sell water, handbags, fans, and stuff at every stop. 3. Day 2 - we waited 45 minutes for the bus and then decided to walk. 4. The upgrade to get the skip the line - Vatican Tour and Colosseum Tour was worth the extra $$ 5. You can take your ticket directly to the Coliseum box office - you don't have to go to the bus offices. It was a good way to see a loop of the city if you have a short time in Rome.
