You can't beat the location of this hotel, close to all the biggest attractions but still set in a relatively quiet and peaceful area. The staff needs to buzz you in to the building so we felt very secure. We had the family room on the first floor and were pleased with it. There were two bedrooms, each with two twin beds, very high ceilings with chandaliers, windows opening to the courtyard in front of the hotel and the small canal on the side of the hotel. The first night I made the mistake of leaving the windows open and found that the boat traffic (deliveries and trash boats) start very early and don't mind making some noise. One morning I just stuck my head out the window and watched the boat traffic for about an hour (I guess I am easily amused). It is amazing how they maneuver the boats, some of which are fairly large, in the narrow canals, with lots of boat traffic, mixed in with a good number of gondolas. We took a gondola ride from right next to the hotel through the smaller canals, we paid $80 Euro for a trip of about 35 minutes. That is the economy tour and they tried to get us to go for the $100 Euro option. I would do it again even though it was expensive. Get your Vaporetto passes ahead of time for a discount on a site called Venice connected. That site also has a virtual interactive walking tour in which I walked from San Marcos to the hotel and it made it easy to find when I actually arrived. Its easy to get lost in Venice, which is OK unless you are carting luggage with you, then it wouldn't be fun.
Here are the easiest directions to the hotel: Get off the Vaporetto near San Marcos Basilica, walk through the Piazza San Marcos (facing the front of the Basilica) and go to the left of the Basilica. Pass a small raised fountain area guarded by two stone lions and you will see the Hotel Concordia on your left. There is a small road or alley that actually splits through the Hotel Concordia, take that straight for about 100 yards, it is extremely narrow, single file in each direction, pass the hotel Monte Carlo, when you get to San Zulian church on your left, turn right onto Campo De La Guerra and the hotel is on your right just before you get to the canal.
