How to find a place in Venice

The two photos above (I'd like to have put them side by side, but I don't know how) are of Campiello del Remer. There is a bar/trattoria here that has many recommendations. But how do you find it? If you use Googlemaps, you will be taken to one Campiello del Remer in San Polo, just south of the Church of San Polo. It's not that one. If you use ombra.net, [go to Venice Street Guide and enter 'campiello' in 'Type', and 'remer' in 'Name'; click 'submit'] you will find that there are at least three campielli of that name. Unfortunately, ombra cannot find more than one feature of a given name in each sestiere, whereas those familiar with Venice will know that you can find several features with the same name - e.g. pestrin, pistor, mezzo - in each sestiere. You may know that the one we want is in Cannaregio. [If not, this will take longer.] So you will click on the campiello in Cannaregio, and the map that appears will show you a spot near San Marcuola. This is not the one we want! [You could check on veniceconnected.] You will see that the search found 15 street numbers listed as being in 'Campiello del Remer'. If you click on the arrow to get the drop-down list of numbers, you will see that they are in three groups - 1574-1580, 5694-5698 and 5714-5716. The first set corresponds to the campiello near San Marcuola. The second set happens to be the one we want. Click on any number in that set and 'Submit'. The map shows you the Campiello del Remer near the Rialto Bridge, which is where the above photos were taken. The third set of numbers is in the same campiello. But that's Venice for you!
