Sara and her family are extremely welcoming and helpful when visiting Venice. She was very willing and prompt to provide all sorts of recommendations about how to travel to and around venice. Everyone should follow her restaurant recommendations that she has on the cork-board. They are phenomenal, I made a Google map of the locations as well to help us find them:

They are in the "RecommendedRestaurant" layer. There are other layers of fabric and vintage stores we also found in Venice. Venice is a great place to explore, but you should allow many days to really explore it, maps only get you so far.

With all the great food we ate, we were actually glad to get the exercise climbing the stairs to the top (4th) floor where the apartment is. The view from the apartment is nice, but not of anything really breathtaking, you'll have to explore Venice for that.

The first night we were cold, but we were there in late-October and they weren't allowed to turn the heat on until about that time of year. Giovanni was very prompt in coming the next day to turn on the heat for us, so no problem there either.

The only recommendation we would have for couples is that the bed is not good for people who like to be close and cuddle in bed. The mattress is actually 2 separate pieces that easily separate in the middle of the night, usually with one-half of the couple landing in the crack. If you're the type of couple that sleeps fairly far apart, you'll be fine. For us, we discovered the futon in the living room could be unfolded, that was much more comfortable for us to sleep on.

Also, make use of the Moka pot for making espresso. Was my first experience using one, and now I'm going to buy one for home.

The location was great as well, being close to big square off a major row of stores near Rialto Bridge meant it didn't take us too long to figure out the basic way back to the apartment. Provided we followed the signs to Rialto, we could always make out way back without having to consult any maps.
