Great flat right in the heart of Athens. Walkable to the acropolis and the agora, and about five minutes walk from a major metro station. Travel from the airport was easy. One train, no transfers.
The flat had a wonderful balcony to sit and watch the city and enjoy the vibrancy of Athens.
Communication from Maria was excellent. She sent a detailed list of recommendations and travel instructions before our trip. We were greeted when we arrived and check in was very easy. She checked in during our three day stay to make sure everything was going well.
Highly recommend if you are thinking about Athens. Only downside was that since it is right in he heart if the city, traffic noise was noticeable at night. Not a big deal for me but those with small children or sensitivity to noise at night might consider ear plugs to accommodate at night.
