The location is great: close to the biennale and downstairs, there's a nice Osteria that has great food and pastries. I could come there again when traveling alone or with a friend. I was happy to find some additions like wifi, shampoo, soap, a hairdryer, and even a laundry machine in the flat – all of which weren't mentioned in the ad itself.
One feedback I would give is to add the tourist tax (5€/night up to 25€) information in the flat info. Or charge couple of euros more and pay the tax from that.
