medium sized microfiber-towel: In my experience, most hostels provide hostels, yet some don’t or charge extra. Apart from getting dry after a shower, these also come in handy for any swimming-related activities or in the gym. Initially, I made the mistake of bringing a terrycloth towel. This turns out to be a mistake because those towels take up a lot of precious space and don’t dry quickly enough (carrying wet towels is a bad idea, mold and bad smells await those who overdo it). Microfiber is the way to go. Take this model as an example; I have to admit though: these have to be washed frequently and don’t feel particularly great on the skin.
