My husband and I spent three nights at Lorenzo's wonderful flat. As others have mentioned it is extremely centrally located (around the corner from the Duomo) and about ten minutes by foot to the train station. Lorenzo was a breeze to communicate with and always immediately responsive; he gave us great tips for food nearby to the flat, and we also just enjoyed chatting with him when we met about Florence, travels, etc. Wouldn't hesitate to stay with Lorenzo upon returning to Florence.
