Konstantinos's place was perfect! We spent two nights in Athens and were able to check off everything on our list of things to do and see, all within walking distance. His place was a 3 minute walk from Syntagma Square bus station, and he met us promptly as we arrived to let us drop our bags off early in the morning before check-in. Once we got in the room, it was very clean, stylish, and has a huge balcony with a great view of the Acropolis.
You're missing a great opportunity if you don't stay here!
