I recommend the cafe au lait. Its very strong though so dont get it if anyone in your home doesnt like the smell of coffee!
We also like Tutti Frutti, Orchard Pear, Home Sweet Home and Cranberry and Orange (nice at xmas). I have the baby powder one in my airing cupboard with lid off and it makes all clothes smell lovely and fresh.
Prob best to go smell some in shops and write down which you like then search online for best prices.
