Although I didn't get to meet Thomas when I arrived, he provided me with all the informations I needed to do my check in.
I used to bus from the airport to the apartment. It only cost 5.50€ and was 1h long. Pretty good deal.
The place itself is great. It's bigger than what I was expected. There are lots of elements left for you to use such as, coffee, tea, salt etc etc. The location of this place is amazing. You will able to find all the things to visit at less than 20min by foot. There's a market at 2min and the prices are so cheap! There are also lots of restaurants around or you can simply cook yourself a meal with the little kitchenette.
There wasn't much noises, very calm area and neat place.
When I go back to Athens that's where I will go back for sure!
Thanks Thomas for your kindness.
