This is probably the best location in Venice to stay. It's very close to Rialto Bridge and also very close to San Marco Square. Because it's close to Rialto it's easy to find your way in the maze of narrow streets. The apartment is big and spacious and has air conditioning and a full kitchen. It's fantastic!
Please know that it's up two flights of narrow stairs, which is the normal in Venice. But if you are mobility challenged you might have a hard time with the stairs.
