I had an amazing stay at Anna's. Anna and her son Alberto are warm, gracious hosts who really made me feel welcome, and were always quick to help with everything I needed. The apartment -- on two levels with a covered balcony overlooking the courtyard -- is incredibly lovely and charming, fairly temperate even on the hottest days, and fully equipped with kitchenware, linens, everything. It's located in a quiet, relaxed neighbourhood a short walk from the train station and all the sites (and also one truly superlative gelato shop). I highly recommend this place, and would happily stay here again :)
