Marcella's place was very clean, a good location within 20-25 minutes walk of pretty much everything in Florence.
Marcella thought of everything - from chocolates upon arrival, to spare toothbrush/paste, to umbrellas (if needed). I did laundry - although as someone else noted before, it is only a washer and the choice for drying is a rack Marcella has in the room or a self-service cleaning nearby. I was there for a week, and had the time to let the clothes line dry over two days.
Bathroom is small (think smaller than cruise ships), which was fine with me, but anyone who is bigger might want to think twice.
My stay was wonderful. The room met all my needs - in general my attitude about traveling is to spend as little time as possible in the room and get out and see the city. This was perfect.
