Translation of avocado in German

We drove to the airport to do early check-in but it went so quickly that we had four hours left before our flight departed. We therefore took a cab back into town and visited the local market.
We really felt like being in a stupid tourist attraction. The environment was very beautiful but the mass of people would ruin our special moments. Anyway we had one more surprise on the way back.
The biggest city in Germany is Berlin. The other big cities are not as big but some of them are really nice. And especially the smaller cities here are very charming and worth visiting.
