We had a great experience in the apartment!
It was very well equipped, we had everything we needed in the kitchen, the whole place was really spacious and the AC worked perfectly for the summer time in Athens. It has good amenities such as a big fridge, big TV and washing machine.
The flat is exactly as it looks in the pictures.
It was only a 5 minutes walk to Sepolia metro station, two different supermarkets, shops and ATM. From Sepolia it's only a 10 minute ride to Syntagma or Acropolis, both in the centre of Athens.
We would definitely recommend anyone who wants to stay in Athens to stay at this place. Specially if you're looking for a long term stay.
