About host Nicolo - he is great host, he knows Venice very well being brought up there. He gave great tips on things to do, restaurants to go to and places which are must visit and less touristy.
About the location, it was great loacation, very much away from crowded touristy area but a 5-10 minute walk from station, no water taxi required. The apartment/house was in the Jeweish Ghetto area which is still much cleaner, less touristy and great old restaurants. Bagetella right next door is a must to go for great sandwiches, pannini and drinks.
About the house, much better than described. Cleaner, convinient for 2-3 people and all things were available in the apartment. Bed was great, living room was great, we did not use much of kitchen but it was small but sufficient. No complaints about house. Check in and check out was easy and on time.
