We really enjoyed the walking tour. Having been to Florence before and seen the sizes of some of the tour groups, we were pleased to find ourselves in a small group with a really well informed guide. The headsets are a bit of a nuisance, but even in a small group they are probably necessary in the noisy streets and at the Accademia. It was great to go past the queue and straight into the gallery! This is well worth the money - I would certainly book a different tour with Viator when next in Florence.
