I stayed at Giovanni's place in early July and found it to be the ideal refuge from the heat and humanity of high tourist season. The location just steps from the Uffizi was ideal: the charming (and relatively quiet) Via Lambertesca boasts a great gelateria, deli and pizza place, among other promising eating establishments I never made it to. Giovanni was easy-going, available (he lives upstairs with his family and runs his dad's jewelry shop downstairs) and helpful with dining suggestions, etc. The apartment was spacious and had everything I needed, including a fan (no A/C) and a Tv to watch the World Cup. I would rent this place again next time I'm in Florence.
