Not a boutique hotel, and not a 4 star as rest of world understands.
The hotel seems to have applied 'boutique' as presentational spin to try to paper over how old it is.
Flying out of Florence airport in the morning, we just wanted somewhere reasonably central for 1 night.
While lobby and some upper corridors look quite nice, the moment you get into the rabbit warren to reach the bedrooms it becomes clear how old it is. (There is a lift but it is tiny & ancient, you need to carry bags up a flight of stairs from lobby first, then up and down stairs again to reach many rooms)
The room we were given simply did not match in condition, upkeep or level of comfort the website pictures/description.
When we challenged this we were told the hotel was fully booked, and nothing could be done (it was now quite late at night so we decided we would just go to bed).
It smells old, not in a good way. Especially in rooms and corridors, less downstairs.
Overnight we then noticed quite how hot and stuffy the room became, despite having the A/C turned on (utterly ineffective) and noticed how dirty & worn the room was generally.
Bathroom tiny, about the size of a small wardrobe.
Reception suggested we visit their 'wonderful roof terrace with an honesty bar'. What we found: Ashtrays full of cigarette butts, rusty empty fridge. View certainly not incredible.
Main complaint: Quality simply does not match photos description. Not boutique, not 4 star (has bidet to tick box)
