I only gave the house 2 stars because the apartment in itself is amazing. It is big, spacious, with wonderful furniture, and beautiful, well-curated accents.
However, the service is terrible: as soon as we arrived (we were five people) we only found one big shower towel. The host Riccardo, while was very kind, was eminently unhelpful. To get the towels we had to find a secret drawer to get a key to the service room, which was quite fun for my little sister but not so much for the rest of us who couldn't shower until 22. This was just the first of a series of problem, the main of which was that the hot water only worked in the main bathroom and that the water line in the main bathroom was broken and flooded the bathroom every time you showered. I asked again for help and said that we would have been out for the whole day the next day and that they could come anytime to fix it. We came back and nothing was fixed, Riccardo said that he couldn't let the plumber in that day and that he needed a part. I asked if it would have been fixed the day after and I received an "Of course". When we left it hadn't been fixed yet.
All things considered, it wasn't tragic, those of us who didn't mind cold water showered in the other bathrooms and the others mopped the floors after using the shower, but still, it's not something you want to worry about while on a relaxing vacation.
This was just the main problem, but there was a slew of broken, non-functioning things: lights, plugs, air conditioning, disappearing WiFi, and so on. Also, the garden could only be used by asking permission before.
All in all, a beautiful facade barely covered a very uncomfortable apartment, for which 350 euros per night is way too much, especially considering the abysmal service.
You leave with the feeling that you have been jerked around from the beginning to the end, albeit in a beautiful apartment. It started when he asked me if we wanted to take the stairs despite the luggage just because he didn't want to show me that you had to pay 20 cents to work the elevator and ended with me asking for an invoice which "of course" I'll never receive.
