Viola's apartment is in a quiet neighborhood, not far from an Orthodox church and a school. We weren't afraid to go back to the apartment late at night, as the neighborhood seemed really friendly. There are many stores, pharmacies nearby, and on Wednesdays there is a market with fresh fruits, vegetables and seafood below the block.
The apartment is clean, modern and well-maintained. Viola is a great host, she responds quickly and is always ready to help or send appropriate assistance directly to the apartment (we had a problem with hot water for a moment, but Viola responded quickly and the problem was solved). The apartment has a great working air conditioner, an Italian coffee machine, a well-functioning washing machine and a really great shower with multiple modes. An extra plus for a very comfortable and large bed. Netflix access was also a nice addition.
It's a little farther from the center of Athens, but it's only a 15-minute walk to the metro, and when you like to walk, you can easily reach the most important places on foot. The apartment is also close to Lycabettus Hill, where you can go for a beautiful sunset and from which you have a great view of the Acropolis and other major Greek sights.
I highly recommend this apartment, it was a pleasure to return to it and relax in it after a day of sightseeing.
