We had a great time in Maria's flat. It really is a very cosy and tidy place. It's located in the ground floor, so no staircaises for heavy suitaces. The communication with Maria was easy and it would have been a pleasure to meet her in person.
You can easily go from there to the airport with the local airport bus. You just need to buy the tickets beforehand at some other bus station (for example at KTEL, the central one down the road). It only costs 1,50 Euro per person and you get there in less than 15 minutes drive.
