Andrea 's place ranks up there with the best: it is as advertised; clean, convenient to the train station and to the sites, abundant restaurants and food markets nearby, an attentive host who gets back to you immediately should you have a question or problem. Kitchen is well-furnished.
The only negatives are the lack of any food-prep area (unimportant if you don't cook any meals), and an erratic water temperature in the shower. Fully recommended with 'negatives' above noted.
