This apartment was absolutely wonderful to stay in. It's located in the heart of town but the bedroom is quiet and relaxing, and the living room is large enough to make you want to hang out in the flat. It's all very clean, a very nice shower, and a cosy bedroom.
The location is beyond convenient. Apart for a very close by Michelin-listed restaurant (Nolan with probably the best Greek-Japanese fusion you could imagine) there are a multitude of restaurants, stores, cafes and tourist attractions.
Beyond the great location and the cleanliness, there are also thoughtful touches such as coffee pods and books left for the visitor, as well as local tips and an already set-up Netflix account on the TV (for the chilling).
If there's anything to take note of, it's that the wine bar across the road, which is very inviting, can be heard from the living room until late at night - if you're not making any noise - but this was easily ignored and can't be heard from the rest of the flat.
Recommended as a great place to stay in Athens.
