Our guide Alessandro was fantastico! My wife has limited mobility & this is a three hour walking tour. She was worried that it might be too much & was concerned she might hold up the group. We were going to explain this to the guide & bail out if & when it became too much. Fortunately for us being low season we were his only party. This meant that he was able to tailor make the walk to avoid steeper climbs & try to come out at points to descend rather than ascend. Of course that's something he was only able to do given it was only us. We cannot thank Alessandro enough for his informative tour combined with a pleasant disposition. Five stars all the way!
