I have booked the guided Tour of Galleria Borghese with OverRome a few days Ago. It turned out to be a really enjoyable experience.First of all they take care of you with kindness and efficiency to make your access to the Museum quick and easy ( very nice feeling of being priviliged).Then the visit is very interesting and instructive. The group is kept in small size so that you can stay very close to the guide and easily watch the artworks. The very friendly guide was very competent, you could say she knew the history of art very well by the way she easily explained complex concepts and by the way she put everything in the general context.Also she explained us how to watch the art works and thanks to her I have noticed important details I would have never appreciated in 1000 visits on my own. www.overome.com
