Our biggest issues was the dampness. Sleeping on the cotton sheets which held the moisture was like camping in a rain storm. A small humidifier ran constantly and the reservoir had to be emptied every day. You can not open the windows as mosquitos flooded the place within minutes - blood streaks on the walls show how many mosquitos were killed prior to our arrival.
We rarely slept well and after three of the five nights we left, forfieting our last two nights for a more comfortable place. This may be an issue in Venice if you are on the first floor but this has not been our experience in other Venice flats.
Mario was great at responding quickly. Pick up was set for 1430 at Plaza Roma with Luca. When no one was there by 1440 I called and Luca said he had multiple pick ups and told us to get a coffee he would be by shortly. At 1530 he arrived. It is a short walk to the apartment that is in a great area, close to everything and very quiet.
The place is exactly as described. Nicely layed out, large rooms and quite clean; however we did have an issue with the floors being dirty (wear slippers as socks got dirty quickly) and we had to sweep up nail clipping (that were not ours) in the bathroom.
It is basically furnished with lots of towels, linens and was comfortable.
The bed is very firm, so firm we had to lay the duvets down to sleep on them just to have some softness. It is not for us but some like a very hard bed.
Of all my Airbnb experiences sadly this was our worst and I can not recommend this spot.
