For us it was perfect...air conditioning, lots of space, elegance. It is obviously brand new. Shower was great. Two bathrooms! We really lacked nothing in the kitchen including a Nespresso machine and water boiler for tea and espresso americana (coffee included).
Even the couch bed was above average.
With public transportation (vaporetti) you can get anywhere, or really for the courageous...walk anywhere.
As with all Airbnb we were not impressed with the apparently hidden costs of cleaning (50 eur) and service fee (90 eur) and city tourist tax (did we miss something?). I suspect this is just something you need to expect. I just wish it were visible in the initial cost. Totally not to be attributed to the hosts. I would recommend it 100%.
