We really had an excellent tour with Begona - I don't normally complete reviews like this but I absolutely wanted to do so on this ocassion. We were a group of friends visiting Santiago but, as it was raining, we asked Begona at the very last minute to switch from a planned tour of the old town to a cathedral tour - which she did seamlessly! Begona is absolutely what a top guide should be: knowledgeable, including a lot of interesting and unusual anecdotes and information not found on the standard tourist tours: very helpful, sending us all sorts of additional information on trips outside Santiago, restaurants, best coffee shops etc before and after the tour itself and patient - as she tried to keep our group vaguely in line and together! Thank you again Begona for helping to make our trip to Santiago so memorable!
