Nikolas was there to meet us and was extremely welcoming and accomodating. He gave us lots of useful advice about getting around, and tips on using public transport. The flat is ideally situated for access to the Acropolis, and is literally 3 minutes from the new Acropolis museum. We loved how easy it was to get to the Plaka, the Cine Thisio open air cinema, and the metro line to the beach. It's really handy having a supermarket just 2 minutes from the front door.
Nikolas' flat is a perfect base, and has all that you need for a comfortable stay. Bed was comfortable, there's a washing machine that Nikolas provided washing powder for, and a great little kitchen. I would definitely stay here again if I was visiting Athens.
