A friend and I are leaving in a couple of days for a month of travel across western Europe, starting in Barcelona and winding our way up towards Copenhagen! This is the first time either of us has done unstructured travel like this, so while we're both excited, we don't know the best way to go about finding accommodations. We're probably only going to spend 2-3 nights per city, so we're going to go through a lot of different places.
I plan on using Airbnb to find most of our destinations. Any tips for how to most effectively find comfortable places to sleep during this whirlwind adventure?
