The Ruthensteiner was great. A big common area. Musical instruments on the wall for public use. A nice kitchen, plenty of bathrooms, great storage options, 24 hour reception with helpful staff, two nice courtyards, strong wifi signal, free computers to use, close to the train station. What more could you ask for?
The Antico Capon is in a great location. It's easy to get to with the directions they give you on Hostelworld. The hostel is in a cool little piazza that has restaurants, pizza shops, gelato bars, regular bars, a market, and a drinking water fountain. Since Venice is a walking town, it's close to everything. Every major site is withing 15-20 minutes walking, but since you're distracted by the sights of Venezia, none of the walks seem that long.
This hostel is in a great location to everything we wanted to see in Istanbul. The staff was cool and helped us with whatever we needed. Helped us book a Turkish bath and also set us up with a shuttle back to the airport.
Great hostel. The beds were comfortable. There were huge lockers. The staff have all the info on popular spots and cool places to eat. The hostel is less than a minute's walk to the underground. Very nice place.
