I stayed 2 nights at Charis aparment with my partner and it was an amazing experience. The location is perfect with being in between the central and alive areas of Plaka, Syntagma & Monastiraki. Being on the 6th floor and with a panaroma window you have a perfect view of the beautiful monument Acropolis. Also with the bed angled towards the window you have the Acropoli view even when waking up and going to sleep.
The apartment is newly renovated with very stylish interior, such as marble section and cosy lighting.
The host Charis is very friendly, helpful and quick to answer.
