We have a very nice stay at Elisabetta's appartment, which is located 5 min from the palazzo dei congressi... so, very well in case of an event organised in this place, or during the mostra. The waterfront is also very close. It's a very quiet place, quite large, very clean and practical. A small terrace helps you to have your breakfast outside when the weather is good, wich often happens in the Lido :) The reception, by Elisabetta, was sympathical and helpful.
A good place that I recommend !
