Location is amazing... just around the corner from the Duomo and within walking distance of pretty much everything! It was also just a short walk from the train station. Communication with the host was excellent, and I received answers to my messages immediately every time. The apartment is spectacular -- spotless, excellent layout, comfy bed and thoughtful touches throughout. Couldn't be better. Highly recommend!
My one and only suggestion is that guests bring earplugs or a noise machine for sleeping because even with window shutters closed street noise is significant in this busy area. The Hard Rock Cafe is close by and we heard loud partiers outside into the early morning hours.
