We had trouble with the Airbnb app once we arrived in Europe. I couldn’t message Efthimis to tell him our flight had been delayed from our first stop. We had already told him we had a late arrival but the delay put us arriving at 1 am Athens time. When we landed I asked my mom back in the states to log on and message him and tell him we were running late. I felt horrible about making him wait so late to let us in but he still greeted us at 1 am with a smile and was super friendly with us and very helpful showing us how to get into the building, how to turn the hot water on and how to get into the apartment. We felt right at home and his place looks just like the photos. He sent us a long list of suggestions of restaurants and bars in the area and overall was super pleasant and helpful host. I couldn’t recommend his place more for your trip to Athens!!
