We have had an excellent stay at Grigoris's. Its a hidden gem in the center of Athens and you couldn't be more central as everything is at a stone's throw. Grigoris was an incredible guest - there was cooled wine in the fridge for us, beer, crackers, nuts, he even gave us 2x breakfast vouchers for a cafe nearby. The view to acropolis is just impeccable and his personal taste is incredible, as I could spot some art pieces from some local and global artists inside the flat. There were some high quality sleepers, 100% Egyptian cotton towels, a security guard in the building and finally to mention that the place was spotless and immaculately clean as you could see it from the marbles on the floor!!! I would definitely like to stay there in the near future.
