The apartment is located very close to the center, within walking distance of all the main historical sites, museums, and parks. It is also about 10 minutes from the metro if you need to go somewhere beyond the city center. Just next door to the flat there is a huge supermarket, which is super convenient. You will also find plenty of coffee shops, restaurants, and bars around, especially in the adjacent Metz neighborhood, just a few minutes away.
The communication with the hosts was quick, easy, and pleasant. As a frequent visitor to Athens, I highly recommend this apartment for long-time stays, but I believe it would be also great for short ones. Many thanks, Sofiana and Susanna!
