Next Summer I plan to visit friends in Norway, Finland, and Germany. I can’t wait!

Since I expect to fly Icelandair, I’m considering a stopover in Reykjavik. Icelandair charges little to no extra for an overnight (or many night) stopover in Iceland. I’ve always wanted to go to Iceland, but my time is limited. Airbnb options look quite reasonable, but car rentals are on the steep side, and I assume gas and food is expensive. I’ll be traveling solo the end of June.

Anyone done a one-night stay in Reykjavik? Do you have recommendations?
