We had a lovely stay at Roberta's, the location is perfect to see the Old City with some bakeries and a supermarket very near by, a food market round the corner, the cathedral visible from the balconies and a 5 minute walk to a busy street full of bars and souvenir shops.
A wonderful mixture of museums, galleries and restaurants within a 10 minute walk. The rooms are beautifully decorated and clean, there was even a chess board and coffee.
I would highly recommend staying at Roberta and Maurizios, lovely people and a lovely stay!
