I stayed in Settignano for six nights and had a great time.
For me, the location was perfect. I had been travelling for six weeks before arriving here, and always staying in cities. Settignano is 6km out of Florence, on a hill with olive groves and wineries, it is beautiful. It is a small, but there is everything you need here- a nice bakery/shop, good restaurants, and public transport into florence. 15minutes by bus which runs frequently until 10pm and drops you within walking distance to the Duomo.
The room was really nice. Good size, with nice bathroom. Clean and tidy. Easy to find, and located on a quiet street. The weather was hot during my stay, but the room had a fan and was quite airy.
I did not met Lucca, but I met his mother and his sister, who were both very kind and welcoming to me. I saw them each day and had coffee with them. They welcomed me into their home, and it was an experience I had not had yet while I have been travelling.
The information Lucca sent me before my stay was great. Recommendations for restaurants in Settignano and Florence, and also a list of walking itineraries which are worth doing.
Overall I thoroughly recommend.
