We enjoyed our stay in the beautiful Sokol apartment.
It is exceptionally well laid out and tastefully decorated.
The terrace is beautiful and we had our breakfasts and dinners while admiring the acropolis.
For access from the metro we recommend metaxourghio station which is only 7 minutes from the apartment, taking 2 flat streets and having real sidewalks and which lead to the main square. This place therefore includes the subway station but also the bus athens tours (take the blue color which are more frequent). These buses allow us to have a glimpse of the entire city from the platform and then redo the route by stopping. To go to the acropolis is also the right solution.
We strongly recommend Sokol's apartment.
