Ourania came to greet us personally and provided us with good information on the local transportation. We took the airport metro directly, there is no need to spend on additional metro fare for the our whole stay since her place is within walking distance to most attractions.
Ourania has thoughtfully stocked up her kitchen with bread, eggs, cheese and juice - really helpful for our next day breakfast. She has also helped us to arrange taxi transfer to the airport for our departure on 1 May since there may be a public transport strike.
Overall, great location, cosy homey place with everything well thought out and a fantastic host!
