Roberto, I would like to thank ANDO for the kindness, efficiency and warmth. I appreciate the flexibilty of your tour, being able to choose wether to follow the group or to go by myself according to my needs. I also underline your attitude in building a group, putting together people mostly unknown each other, ending up as a team.Thanks to this experience, I learnt to claim the respect that polite and correct guests deserve from tellers or service supplyers. Best regards Mauro F.
