Katerina is a great host and her place was incredible. The flat is easy to get to using the metro. It is clean and a lovely peaceful place to come back to after a busy day of sightseeing. The outside sitting area was a bonus and is a great place to start your day (and is exactly like it is in the pictures).
Katerina met us at the flat and made us feel at home, she provided us with a map showing where all the local shops and restaurants were and recommended two local restaurants both of which were excellent.
The flat is a few minutes walk from the Acropolis and you can walk to all the main areas in around fifteen minutes. Or if you are feeling lazy the metro is at the bottom of the road.
We had such a great time that we booked the larger apartment for the rest of our stay, and would definitely stay again when we return to Athens.
