Tuk-tuk drivers around alfama quote 50-80 euros for 30min rides. That's insane for a glorified golf cart

Fair price is 20-25 euros max for standard alfama loop. Start at 15 euros, work up slowly. Half will say no but someone takes it. Hills are steep but totally walkable if not rushed

Better yet take bus 737 up the hill for 1.60 euros. Same views, fraction of cost, runs every 15min from rossio
