Grigoris penthouse is basically a dream. It's even better in person than in the photos. A massive space in the heart of Athens with the best views. You have absolutely everything walking distance, from the major touristic sites, to the best restaurants, supermarkets, public transport... It was totally worth it. And Grigoris was a gracious host, who picked us from the subway station, did a super smooth check-in full of useful tips and advice. It's definitely a treat for those who truly want to enjoy the city to its fullest.
