We really enjoyed staying in the Casa di Anna for 7 weeks in Feb-March 2022. The apartment is supremely comfortable, especially the living room furniture and dining room chairs. The beds are great. The location is excellent - a quiet street within easy walking distance from all major sites and the major pedestrian thoroughfare (via Maqueda). Excellent restaurants and cafes within easy reach. (Our favorite was Trattoria da Massimo).
The kitchen was small but had everything you would need for basic food prep and cooking. We cooked in several times over the course of our stay. We had friends visit for a short stay and the apartment was perfect for two couples - each bedroom is on a separate floor with its own bathroom.
One thing to be aware of is that there is a construction site just outside the apartment, where workers are restoring a centuries-old building. When we were there it was cold so we kept the windows closed and didn't hear much noise at all during the day. It was actually really interesting to watch. At night it was very quiet. Although the apartment does not have any view to speak of, it is extremely quiet at night because it does not face the street. We would definitely stay there again.
