Tornabuoni's place is a boutique hotel on the second floor of a building. You go inside a main door into a shared living room space, with three separate bedrooms that connect from there. Each bedroom locks from the living room and has it's own bathroom. Other guests stay in the other two rooms. This isn't very clear from the pictures on the booking reservation, but it was perfectly okay.
Our room and bathroom were very clean and nice! There was plenty of space for two people and we felt very safe, separated, and clean there. It's also just three blocks from the Duomo, so a great location in central Florence.
Great place, Tornabuoni!
