Caterina's apartment is, in fact quiet and central. It is close enough to the train station that we were able to walk there with our luggage in tow. It is also within walking distance of all of the main tourist attractions. The apartment itself is in a building that dates back at least to the Renaissance. As such, it has a vaulted ceiling, stone arches over its doorways, and plenty of character. As a side effect of its age, it also has a small bathroom with a folding shower and drains that are a little slow. Caterina, our host, lives in the apartment above us and was very friendly and helpful.
