We had a pleasant stay in Ostello S.Fosca. The location was great for the price since it was on the island of Venice rather than being just outside like most other hostels. The hostel was fairly clean and we didn't have any specific complaints. The place is also used by students as residences so it ensures a friendly environment.
Our stay in Afossi Hostel was great. The room was really simple and was designed only to fulfill the main needs of the customer, however it was clean. The best thing about the hostel was without a doubt its location. All the main tourist attractions are in walking distance and the place is safe. One other thing that is worth mentioning is the friendliness of the hostel owner lady. She greeted us with a warm welcome and she was very helpful about the city.
