We stayed 2 nights at Letizia's apartment near the Pitti Palace. The location is ideal and I would say location is its best feature! 30 seconds walk to the Palace and Gardens. Ponte Vecchio, San Spirito plaza are 5 minute walks. All the sights on the other side of the Arno are easily walked to. We also enjoyed the outdoor patio.
The apartment is as advertised but could surely use some freshening up (fresh coat of paint, new couch cushions, better lighting - despite airbnb pics that look very bright, spruce up patio).
Overall, it was a comfortable apartment for 2 nights with a fantastic location.
