This apartment is in a great location in the Castello labyrinth, reasonably central but quiet and away from the main tourist drags. The Rio out back is quiet and beautiful. A perfect location for visiting the Biennale at Giardini and Arsenale. The supermarket at Rio S. Agostin is a two minute walk. I timed a 7am walk to S. Lucia station at 35 minutes, despite a few wrong turns early on.
After some messaging, our host, who introduced himself as Lucio's son, met us off the Alilaguna at Ospedale and led us to the apartment. He was very polite and informative, and the whole check-in process was smooth. On departure we were able to leave bags in the apartment until lunchtime.
The apartment was very clean, comfortable and spacious for two people, one in the bedroom, one on the bed-setee. Being on the first floor there was no problem with the acqua alta. All the equipment we used was clean and in working order, including wifi, dvd, tv, oven, iron and heating. One or two of the electric wall sockets were loose, which may need some attention.
Coffee and tea were provided; a kettle would be normal but we used the small pan which was ok. Bed linen and towels were clean. Also provided were shampoo, shower gel, hand wash, washing up liquid and tissues - these are minor items but providing them took some of the shopping hassle out of our stay.
Only after booking did I notice that smoking was allowed at the apartment; this may have had a bearing on my choice, but there was no residual smoking smell in the apartment whatsoever. The apartment may be due a repaint soon. The ground floor entrance hall probably needs some work to the electrics and painting, but there is a wonderful worn stone staircase leading up to first floor (no lift).
Overall, a very positive experience and I would stay there again if the apartment was available.
