This place is the best one!!
Katerina is really a great host.
The appartement is well located, 3 mins from the metro station and the connection to the city center is fast and easy.
The place is VERY clean and nice. You will find everything that you need inside, and in case of any question, Katerina is always reachable.
If I will have to come back to Athens, no doubts it will be here.
