We had a wonderful stay in the apartment! His colleague, Marco, met us at the scheduled time and it was very easy. We found the apartment just off of the Central Market (Mercado Centrale) which has a wonderful food market upstairs for enjoying a casual (and delicious) lunch or dinner. The apartment can not be more centrally located! It is located on a side street where the outside market vendors (for leather goods, clothing and souvenirs) keep their carts in the evening. The sounds of the market can be heard from above on a beautiful summer night. The apartment is on the second floor (considered third floor in the US). We used the washing machine while visiting (search online for English directions on how to use it) and we were happy to hang our clothes out on the drying lines that run parallel to the window. It was very authentic! Would stay here again while in Florence!
