Maria-we stayed at SRS Hotel Saturnia International. It's not really a luxe place, but it was relatively reasonable in price and just a short walk from St. Mark's square. The concierge there was very helpful and gave us lots of information about available tours, etc. I'd say the hotel is equivalent to a Radisson in the US, but obviously the building is older than most hotels here. Our room rate of around 220 Euros included breakfast and free internet. Venice is very, very, very expensive!!! I nearly croaked when I had to pay over $10 for a coke.
