I'm going to say this again at the end of my post, but here goes. Coffee tastes are very individual. There's no 'right' or 'wrong'. I am not not not being critical of other peoples' preferences.
BUT I prefer an old-fashioned cone filter wth papers, perched over a clean warm jug. No hotplates or any fancy warming devices. That way, the coffee isn't stewed, which sometimes happens with a cafetiere. And there's a smaller chance of stray grains in the cup. level dessertspoon of fine ground coffee per person for a mug; less for a smaller cup. If you like it strong, that is. You can always add a bit more hot - just off the boil - water if you like it weaker.
Can't stand Starbucks' or Taylor's coffees. Starbuck's in particular I find coarse and over-roasted and just generally nasty tasting. And Lazy Sunday - no. (To me, it's the equivalent of milk chocolate - which I loathe - as against dark and crisp and bitter plain.) I wouldn't use Lavazza with a filter paper for different reasons - it's designed for espresso. But I'm not saying I'm right - I'm just saying what I like. I KNOW we all have very different tastes.
Fresh ground coffee is best of all, but that means having a coffee grinder. For ground, I like Cafe Direct's Macchu Pichu. Lidl's single estate fair trade ground coffees (when they have them) are also good and interesting. You might like to find out about different coffee varieties, often based on location: Java is often very strong; Kenyan is mild, Caribbean is very fragrant; south American varieties can have rich flavours without too hefty a kick etc etc etc.
Sadly, ground coffee does go off very quickly once it's opened. (The oxygen in the air interacts with it.) As others have said, keeping it very tightly closed in the freezer is a very good idea.
