Valeria was an absolute delight. First impression - she was so patient as we were running a few minutes late when she showed up (on time) for our tour and did not make us feel stressed at all. We altered our tour slightly as we went along and she was 100% accomodating. We never felt hurried and she was absolutely NOT a "clock watcher" which was so very much appreciated as we were loving seeing that beautiful city through her highly educated eyes. If we were to do it all again, I can't think of a more knowledgeable or personable guide to walk me through "her" city. 5 Stars for sure. Thanks Valeria - what a memorable tour your beautiful city. You made it come alive for us on every level.
