We were disappointed with our stay, but there were good points, and both Valentina and Enrica, who checked us in, were very responsive and helpful. The apartment is really unusual and some people will love the arty design but we found it dingy and gloomy and not very inviting.
The good: wonderful location with great restaurants and bars nearby and walking distance to main sights. The apartment is spacious, warm in winter and the wifi worked really well. Beds and sofas reasonably comfortable, good bedding and towels, milk, tea, coffee and breakfast snacks provided.
The not-so-good: noise at night - apartment not well-soundproofed and there were doors banging and people (staff?) talking in the restaurant next door until 3am, and a loud dinner party in the apartment upstairs went on until after midnight with loud talking and chairs moving until after midnight. Valentina very apologetic and she and Enrica said they would speak to the neighbours (but how you cut out restaurant noise I don't know).
Coffee maker and toaster didn't work properly - sounds minor but very frustrating not being able to make a cup of coffee in the morning without a lot of coaxing of the machine!
Photos on the site are out of date. There is no bath as shown and listed, it has been replaced by a shower. Some of the furniture is different too. The cobbled 'Roman road' is not great for navigating to the bathroom from the bedrooms and leaves your feet black!
