If you mind your budget more than frills, amenities and nice room decoration, Cristallo is the way to go. Located in the very center of Lido, the hotel can be easily reached by foot from the vaporetto pier, the staff is extremely nice (ask them for a room with a windowed bathroom) and, most important since it's Venice, the price is a bargain.
The rooms nothing special indeed but very clean, breakfast is served at ground floor, there is also the opportunity to sit outside in a very little garden. Unfortunately they don't serve true espresso coffee but the rest is quite ok.
