My friend and I (both early 20's) felt perfectly safe when we stayed at Cristian's place in Venice for 3 nights and it completely exceeded our expectations! The place is actually much larger than the pictures and the location is AMAZING, right outside of the city centre but still on the island (which we would 100% recommend because as long as you are on the main island you can walk anywhere). It was quiet enough that we could get a peaceful sleep and close enough to everything we needed (grocery store, restaurants etc), the grand canal was only a 10-15min walk to be at the main tourist bit. Cristian was a fantastic host with quick and helpful responses, he gave us loads of suggestions and was very friendly! We would definitely stay here again if we are ever back in Venice! Thanks so much!
