Great location, very walkable. The bed was very comfortable and it was quite clean. Value wise, I don't think it's worth it. There are hotels in Florence that are probably more worth it with less problems, more amenities for the same price. For how much you spend you tend to expect more.
They provide the BARE minimum, we were staying for 5 days they provided 1 roll of toilet paper. We had to go buy toilet paper, they're very controlling on the temperature controls. God forbid you have more than 3 things running around the house, if you had the tea kettle going few lights on and a iron. The breaker would flip and you will be engulfed in pure darkness, it wouldn't be as bad if you needed to fix it if it wasn't 1 floor down on the sketchiest stairs and needing to carry a ladder down.
The terrace was nice but we were there in December and it was pouring most days. So we didn't get to enjoy it, overall if you're planning on staying in the city it's probably better to book a hotel.
