Apartment is nice and comfortable, equipped beyond any expectations. From ironing board over mosquito repellents to HDMI cable... Bed is very comfortable and everything is clean. There were even some croissants waiting for us on the day of our arrival that helped tremendously to get energized after long trip and feel ready for exploration of city centre. Evangelia responds quickly, readily provides all needed information and is super friendly.
Within walking distance are several shops for groceries and metro station that's three stations away from Syntagma square. You can reach appartment easily by taking a metro from the airport with changing the line only once.
The only down side is the neighborhood, neglected buildings, dirty streets and bad smell in the building hallway. Despite that, we felt safe and would definitely recommend this accommodation.
