Go to Rialto Bridge (walking from Piazzale Roma / train station Santa Lucia or coming with the waterbus line 1 or 2.) and cross the bridge (if you take the water bus you will get off on the right side of the river). You will arrive in the square ‘Campo San Bortolomio’.
There turn left. You will see a small alley (Salizada del font ego dei tedeschi) and a bridge.
On the right side of the bridge there is written in gold letters on the wall ‘COIN’ (name of store). Go to that bridge and cross it.
Go then until the next bridge and cross also this bridge. Immediately after the bridge turn right into the alley (on the corner there is a shop called ‘Clarks’).
Go then until the end of the alley (Salizada S. Cazian). You will be in front of a bakery (‘Panificio’), the alley is called ‘Ramo del Campaniel’. Turn Right.
There is a square with a bridge amd a church behind the bridge. Go to the bridge but DONT cross it! Cross instead the bridge on the left hand side.
When you are on that bridge you can go straight ahead on turn left. Turn LEFT.
You will see on a wall in front of you the street name ‘Riotera die Biri o del Parsemolo.’ In front of that tag ring on the bell of ‘Venice Star / Paduano’
