Fantastic place! We stayed in the apartment for three days in late March.
The first thing that strikes you is the magnificent unhindered view of the Acropolis, which the ceiling to floor windows provide.
The place itself is modern and clean, designed by one of Greece's top architects, nothing is humdrum or ordinary here.
Lots of cupboard space, various food in cupboards & fridge, coffee and tea.
The location is perfect. Took us a leisurely 20 minutes to reach the Acropolis museum and then a few more minutes to the Acropolis itself.
Great authentic Greek tavernas in the area, amazing bakery up the street, subway station is a few minutes walk away and made it easy to travel by train to Piraeus to catch a ferry to Hydra.
Also great experience walking to the trendy Kolonaki neighbourhood for a coffee and then taking the funicular up to Lycabettus Hill for a great view of the city & lunch.
Both Agis and Leonidas were very helpful when we thought there is a problem with the lighting in the bathroom. It turned out we dimmed the lights inadvertently.
The place really made our stay in Athens enjoyable.
