We really loved Margherita's place. Margherita wasn't in town so her cousin Leone met us at the vaporreto and walked us to the apartment (about 5 minute walk). He pointed out some places to eat and provided a map of the city. Margherita had a bowl of fruit and some wine and s few other items upon our arrival.
The location is in a quite area a short walk to shops and restaurants. (I suggest you drop a pin for location when leaving apartment as Venice is not easy to navigate and getting lost is a strong possibility.) Right out the window is the canal with boats parked. It is truly a picturesque scene.
We did find the mattress to be extremely firm and not comfortable. But other than that the apartment is well furnished and a great location and we would definitely stay here again and recommend to others.
