We didn't get to meet Linda, but she was very helpful throughout our stay. The apartment felt like home and was very nice and comfortable. The location is also perfect, as it's quite close to Ponte Vecchio and within walking distance to most places. Florence in general is a wonderful city to walk around and get lost in.
The only issue would be that the shower is kind of small.
All in all, we had an enjoyable stay at Linda's apartment!
