We stayed at Giorgio's apartment for three nights in October and it was exactly as described. The four terraces were wonderful. The two overlooking the canal were perfect for morning coffee and an evening glass of wine. Our two bedrooms were both comfortable and tastefully decorated, and the three bathrooms (one downstairs beside the kitchen and two adjoining each bedroom) were all spotless. Having a washer and dryer on site was another major bonus. Giorgio's location is superb and I would most definitely recommend this apartment to anyone visiting Venice. Giorgio met us at the water taxi stop when we arrived to show us in and came again the morning we left to return our deposit. He is a life-long Venetian and knows everything you might want to ask about visiting his city.
My one thought would be that it was initially quite daunting to receive 31 separate PDFs to read with instructions for our apartment after we booked it. However, the information contained was very helpful, and each PDF was only a paragraph long. I think it might be better if all this information could be contained in one document for guests in future.
