Is it possible to prearrange a taxi for pick up at Piazzale Michaelangelo? We are a group of 6 seniors, one in wheelchair, driving up for the day from Montepulciano. Previously, have had good experience parking at Piazzale Michaelangelo, but obtaining a taxi after arriving there was very difficult and time consuming. (No working local cell phone with us). Would like to arrange a van type taxi for pick up at Piazzale Michaelangelo to go into center. Any suggestions??
