Great communication from our host. The apartment is relatively basic as you would expect for the price - excellent value for money.
The airbnb is in a district just outside of central Athens. There is a bus stop 2 mins walk from the apartment, and the bus takes about 15-20 minutes to get to the centre - where the Acropolis is etc.
Exarchia is a really lively district - I wish we had explored the cafes and bars around here more.
Go to Athinas Olimpias for an incredible and reasonably priced rooftop meal. And you must visit Lycabettus Hill (15 mins very steep walk from the apartment) - there is a restaurant called K Grill at the top - 5 course, €25 euro set menu with wine. Amazing food and views of the city.
Hope you enjoy it as much as we did!
