I second either a moka pot or an AeroPress.
The moka pot would be better if you have easy access to cooking facilities (the stainless versions are also easier to clean, and work on induction).
The AeroPress would be better if you only have access to hot water.
As written above, coffee from moka pot absolutely destroys me. :(
It's too concentrated.
Moka pot coffee is definitely strong. If that's your only coffee maker, I'd just dilute that with more hot water.
An Aeropress is less concentrated in my experience, and it's pretty easy to use. I prefer iced coffee unless it's cold out, so I fill the collector with ice before I brew. The melted water dilutes it nicely, in my opinion.
