Don't drink coffee
You shouldn't drink coffee. It really messes with your brain. If you drink coffee, go for an espresso on Piazza Vittorio Veneto.
If you still want to drink coffee, these are my recommendations. I've made coffee like this for the last year while on trips and it changed my way of experiencing coffee. Use a Aeropress to make fresh coffee, nothing fancy, just a 40 bucks plastic coffeemaker, it's the best! Be inspired by this ultra-hipster video on how to make it. After that get back to reality and check these tips from an interview with the inventor Alan Adler.
My favorite beans are the the Gayo Blue Mountain from Simon Levelt.
If you like making coffee on the go you should have a Jetboil Stash cooker and a Helinox Tactical Field Office. Both have become my favorites during our trip to North Cape.
