The place is clean and well-organized. As described, the penthouse strategically located at the central of Athens, where you visit many key POI like Parthenon, Syntagma Square, Acropolis Museum, Monastiraki Square within 10 mins walking distance. The house has everything you need for a family in size of 4-5 ppl to stay. The host kindly prepare some welcome drinks for us too. There's a roof-top balcony accessible from second floor where you can enjoy the view of Parthenon and Mount Lycabettus at night. Parking is however not easy if you go there by car, we got a parking ticket on the second day because we park on the reserved slot for locals only. Be warning that it could be noisier on weekend midnight from nearby nightclub party if you are not a lover of nightlife.
Overall, we like the place and enjoy our stay at Olala's home.
