We stayed at Costa's flat as the fourth and final Airbnb on our 11 day trip. It was definitely the best one by far!! The flat itself was amazing and ample space for the three of us traveling, but the best part was its location. For this price, you truly cannot be any closer to the heart of Athens. We were very close to a metro station, but we walked most places. It was so easy to get to and was a great space to come back to. Costa was a great host as well - couldn't get much better! When we had some issues with the hot water heater at 12:30 AM, he showed up to help us out. He went above and beyond to help - would definitely recommend this space to anyone visiting Athens!
