We couldn't provide a stronger recommendation for staying at Dionysios' place. Everything about it -- from the house itself, to Dionysios and Ilaria as hosts, to the neighborhood -- is perfect.
The house: The pictures accurately depict what you should expect. The swimming pool, in fact, is much larger than what we expected in the photos. We arrived at the apartment and everything was very clean and there were extra touches from the host throughout -- plenty of linens, toiletries in the bathrooms, food stocked in the kitchen, etc. There is so much outdoor space, between the courtyard in the back, the two roof terraces, and the balconies which are all beautifully decorated with flowers and plants.
One tip: If you are planning to need the fourth bedroom (located in the guest house), double check with Dionysios that it is available as it was under renovation during our stay. However, the three available bedrooms, three bathrooms (including one in the pool area), and two half bathrooms are more than adequate for most groups.
Hosts: Dionysios and Ilaria met us upon arrival, gave us a tour of the home, and gave us tips about the neighborhood and other locations throughout Athens. They also offered to arrange a taxi pickup at the airport to make arrival easy. Dionysios also stopped by a few times during our stay to make sure we were comfortable and enjoying ourselves. In conversation, we mentioned that we wanted to learn more about Greek wines/spirits and that we were enjoying the seafood in Athens. Over the next two days, he stopped by with wine, a mystery Greek alcohol, three beautiful fresh fish, and octopus! Very thoughtful and great hospitality!
The neighborhood: 15 minute walk to Placa/Acropolis and Syntagma Square. We love walking so it was easy to get to all of our destinations on foot. Within the neighborhood is just about everything you might need -- restaurants, cafes, bars, grocery stores, pharmacies, etc. Mets (the neighborhood) has a cool vibe and the people are laid back, young, and very friendly. Mets is also very green and quiet which sets it apart from many other Athens neighborhoods.
Thanks again Dionysios for a lovely stay!
