Can someone recommend hotels so that we can max our 3 full days time? We are willing to stretch our budget in order to visit as many sites as possible. (already bought the tickets for Musei Vaticani. Also going to visit Colosseum, Pantheon, Borghese gallery and a couple of popular outdoor/no ticket required sites if time permitted). On a side note, Is there a difference to purchase Colosseum tickets through https://www.il-colosseo.it/ or https://www.coopculture.it/?? Google said it must be purchased through coopculture. I personally found www.il-colosseo.it website is not easy friendly to navigate the options. We are not planning to join any tour.
What mobile app to use for metro, bus and train purchase tickets? What is the ticket validation process? Thanks.
Also greatly appreciate if you could thrown in some restaurants options.
