You might like to take a look at the Rose Garden appartments in San Stefanos NW. Be careful there are 2 the other on has no beach.
There are only 11 apartments on the site and it feels like you are in the middle of the country but you are only 10 mins walk for the beach.
They are spotlessy clean and the sheets and towels are changed twice a week and there is aircon in all rooms.
The gardens and pool are lovely and do not get crowded.
All the pools in Corfu are free to all but because the Rose Garden is a little off the main drag into town so not many people go there so there is no fight for the sun beds.
The Manager is very friendly and nothing is too much trouble for her. She will keep the bar open as long as you whant her to and then be up the next day to cook breakfast should you want it. Her Greek night BBQ's are to die for and great fun with traditional dancing be prepaired to join in.
The resort is very quiet but there are a lot af bars and restaurants enough to try a different one every night in 2 weeks and still be some left over.
If your daughter is looking for nightclubs then she won't find one, but there are many livley bars to try. The Rose Garden is not to far away from the centre of the resort and I think it would be very safe for them to walk home on their own.
The beach is large and safe as its shallow and there are a few water sports for them to try.
There are not many shops but many well stocked supermarkets in town. A day trip to Corfu Town is a must if you like shopping.
If you like the sound of this you can book the Rose Garden only with First Choice hoildays therefore you only get brits staying there.
It realy is worth a look at as it's the best place we've stayed in for the price
I hope you find something nice enjoy your holiday.
