I think the two folks who own the Giada (Eva & husband) are lovely, but I would never stay there again and do not reccomend it.
Giada is in the middle of the markets, about 5 blocks from the train station. Cabs cannot go there, so you have to lug your stuff either over cobbble streets while dodging trucks and scooters or on the narrow sloping sidewalks, where no native will give you an inch to walk. It was difficult. The room appears very clean, but is furnished thrift-store style. We found a tick on the wall, and I got flea bites all around my ankles.
The shower is a 1.5 foot box that you have to squeeze into through a tiny opening in the corner (tight, even for my size 4 mama). The toilet runs spontaneously. The TV has no CNN or BBC, so no English programs. The "big American breakfast" is runny yougurt, warm sour juice, horrible "croissants," fruit, "Kraft" American singles, and hard boiled eggs & coffee & tea. /no iron available, and none allowed to be used in the hotel. The reception is closed from 11-7, so you cannot get a wake-up call, (we had to sit up all night to make sure we caught our 6 am train to Rome), and the security is extreme (locking hallways, video camaras everywhere), faulty (swipe cards that work occasionally, scary after the staff goes home), and sketchy (locked hallways left wide open at times). The elevator fits 1 person and a suitcase. The "markets" that surround it are not little "gems," just extensions of the area stores, and they all hawk the same things. Boring. No originality. The outside street can smell, at times, of sewage. Barely a window in the room, with no view. Fridge in the room, but not very cold. Nothing in it to purchase. Hairdryer they provide does not work. Rooms are not bright, although, I believe, they are painted yellow. Hotel is hard to spot when the markets are open, as are street signs in Florence, which can leave you wandering the streets. Staff has limited English.
Unique Quality: Staff is either Eva or her husband, and they are sweet great people. They have free internet while the lobby is open, but it will not access some American email providers I found out. They will make you tea during the times they are there if you'd like. They have lots of maps, dictionaries, and umbrellas in the reception, which they will let you use.
Breakfast is free, and if you can eat anything just to fill your belly you may find it adequate.
AC in the room works and works great, but boy is it loud. It sounds like a heavy rainstorm pelting down.
Directions: Across from the ugly church behind the leather coat stand. Which leather coat stand? When you find the bricked-up church window w/ the crumbling bricks (lots of its windows are bricked-up; it must be the crumbly one) across the street from that is Giada.
