I stayed with Marianna for 5 nights.
The room was as described and the sofabed was really comfortable.
The location was perfect in a nice area with lots of restaurants and bars and in walking distance of the duomo.
Marianna was the perfect host: always very helpful and kind, she gave me a nice suggestion for a restaurant and even booked a train ticket for me! Living with Marianna was very easy. Last but not least, let's not forget the beautiful cat, I found it very nice to hear the sound of the lovely paws tripping over the floor :)
