Andrea's flat is spaciou, comfortable and scrupulously clean. It is located only a few steps from the sea promenade and about five minutes' walk from one of the two Ortigia (mini-) beaches. The only weak point is perhaps insuffcient daylight, as the flat is located in the first floor on a narrow street. But that might be a plus in the hot summer season :-). We spent a relaxed Christmas week there and appreciated the functioning heating, not always a given in these southern places.
Andrea is as sympathetic and helpful a host as you could wish for.
Overall: highly recommended.
