Carola is a fantastic host who kept consistent communication with us (even with the Atlantic between us). The flat is awesome with a rooftop terrace that overlooks Firenze. We bought pizza one night and ate dinner on the roof. The flat is on the top floor and there is no elevator in the building - so be ready to build some muscle and endurance. The flat and the building is not accessible to users with accessibility needs.
The room is perfect - there are some tall closets that have keys where you can lock the doors and keep your stuff safe (if you feel compelled to do so). The location is right over the river - easy scenic walks all over but close enough to the hustle and bustle. The windows face one of the main streets so you do hear some street noise when the window is open (a little more muffled when closed). There is a fan for anyone who needs the air movement!
We did have to get used to the shower in the flat. The shower head was in the bathroom without curtains or walls, or a separate space (it's like a powder room or 1/2 bath with a shower head). It was cool once we got used to showering without getting the entire room wet (easier than you think), and actually helped me be mindful of how much water I was using.
Right around the corner from the building is a cafe and a convenient store. Super location! Would stay here again if we were ever in Firenze again!
