One more review on Mac's service:

MAC is a very nice guy, very friendly, attentive, full of good will and good vibes, he knows the city well and has always good tips for his customers, he always endeavours to please them so that they have the best memories of their tour with him. It would be even better if he was a bit better organized because he tends to be a bit messy. But since he is still fairly young, he will learn to improve himself on that point, in his own interest and that of his customers. Ian
