Venice. Should be absolutely lovely at the end of Sept and not as stupidly hot and busy as the Summer. Loads of cafes, bars, restaurants and a great place to walk around. Absolutely perfect for 3/4 days. I would recommend getting a water bus over to the Lido at some point as well as the beach there is gorgeous. Try to avoid the days the massive cruise ships are in town though.
Essaouira - north-west coast of Morocco. Beautiful, sunny, sandy beach but too windy for sunbathing really. Lovely old town with a craft market and a harbour with fabulous fish stalls. Great trekking in the high Atlas about two hours drive away. Lots of lovely hotels and riads. Try Villa Maroc, v old school, v glamorous in a pre-war sort of way.
it is towards the end of sept. We would like some sunshine, to be near some water, ideally to be able to do some walking and some cafe culture. we are wondering about the south of france but open to other ideas in europe. budget top top £1500 for 4 nights. any suggestions - where have you been?
