Free water
Walking round Rome can be thirsty work, especially in the Summer. Near to all the major attractions you'll find stalls selling food & drink. A half litre bottle of water costing 2 Euros.
However, also near to the attractions & throughout the city, you'll find fountains & water taps. These will give you an endless supply of free drinking water. So by a bottle for your 1st drink, don't throw it away & keep topping it up for free.
