Has anyone used "The unofficial guide to the Vatican Museums" app by ItalyGuides.it for audio tour of the museums? We will have just little over 3 hours to see the museums and the Sistine Chapel so we are not sure if we will get the time to go into details of everything. If we rent audio guides from the museums, it will be 7 euros per person. If we use this app, we will pay $4.99 and share the audio tour using a splitter (2 of us). That is the reason we are considering this. Can anyone give a review of this if you have used it or any other audio tour apps from ItalyGuides?
Also, we have Rick Steve's audio tour for the Sistine Chapel.
Thanks!
