I stayed a few weeks to work from Athens and the apartment is just perfect. It is very clean and modern. It is bigger than it looks on the picture and has a great balcony with sun almost all day.
The apartment is very well located in a great area of Athens, from where you can walk everywhere.
El is a great host and her help Nikos were great support and helped with any questions on the way.
Highly recommended and would come back any time when in Athens.
