Stayed at Caterina's apartment in May. It was easy to find and very good info provided by Caterina's daughter (Petra) on how to get there, including water buses etc. We were greeted at the door by Petra who was very friendly and showed us around the apartment. She was very keen to make sure we had everything we needed :)
Caterina was also very nice and showed the children her tortoises and baby tortoises which they loved.
There was a selection of toys available in the garden although we didn't really use these as we were out most of the time.
Apartment was smaller than expected but was fine for us as we just used it as a base for sleeping mainly. Having a washing machine was really handy and it has microwave, hob, fridge and dishwasher. Plenty of towels and bedding were provided as well as washing machine detergent, toilet roll and dishwasher tablets.
One mattress on the double bed was a bit hard (although the other very soft) so could probably do with replacing or a mattress topper.
It's about a 10 minute walk from the vaperretto terminal, as well as many bars, shops and restaurants. It's a lovely walk as well if you go along the front. Plenty of choice restaurant wise and an arcade for the children
The beach is very close as well and easy to get to.
Several supermarkets nearby. We went to the Prix supermarket (5 min walk) but actually there's a much better (bigger and better stocked although prices maybe not as cheap) one (Conad city) on the main street down from the water bus stop.
Several bike hire places within 10 mins walk as well. This is a great way to get around the island and it doesn't really take that long to visit either end.
Venice itself and St. Mark's square is just a 10 minute water bus ride away (ACTV route 1) so it's easy to get back and forth between Venice and Lido. The route 1 bus runs all night as well.
You get the best of both worlds really, a Venice city holiday and a beach holiday.
Be aware that taxis are very expensive on the island. Even though from the water bus terminal it's a max 2 min drive to the apartment you're looking at between 8 and 13 Euro. If you're able to able to walk though it's not really an issue as everything you need is within a manageable walking distance.
Overall we had a lovely stay and Caterina and Petra were very friendly
