I've always chosen villas via either the owners direct www.ownersdirect.co.uk/ or holiday lettings m.holidaylettings.co.uk/ website. Never been disappointed yet. So many apartments etc on there you need an idea of at least what country or region you want to go. I've found things of different sizes etc. we've been to Spain, Croatia, Cyprus etc it does mean sorting hire cars and flights yourself but we prefer to have the freedom. I'm sure you'll find something for all of you.
Would really like to include my Mum on break with us whilst her health still permits, can anyone recommend a website for holiday cottages/villas in Europe please? Or suggest a hotel that would be suitable for all of us, ie something for the nippers but also perhaps a bit of something for the adults as well.
