We stayed in Georgia’s flat with our 8 month old baby for 3 nights. Georgia kindly provided a cot. The location is ideal, a 5-10 minute walk into town, and a 5 minute walk to a small beach. We spent most of the time at Lido Burrone which was a baby friendly beach about a 25 minute walk away. We stayed in June, so it was incredibly hot, and had to plan these walks in the early morning or late afternoon to avoid to worst of the sun/heat (but the flat had electric fans and stayed cool).
The location is slightly different than what is listed on Google maps - walk further than the intersection almost to the end of the road.
The flat is lovely, although a bit tight for a family, so might suit a couple if staying long term. It includes a small kitchen that has two hobs for cooking simple meals. There is an outdoor space that is shared with neighbours.
You are in the countryside so expect insects - mosquitoes, ants, etc. We had an incident where we found a centipede on the ceiling at 4am!
The major negative was the dust that fell from the ceiling. We were constantly cleaning the bed.
We had a wonderful stay in Georgia’s flat and really enjoyed our time in Favignana.
