We can recommend this accommodation.
The host was very quick in replying and even granted us late check-out, which was extremely appreciated and helpful!
The apartment was very stylish, clean, modern and new. Especially the terrace was a huge luxury with a large table for dining, lounge chairs and an outdoor bathtub, with a view over Athens.
The location was perfect us as it was directly by the metro, lots of restaurants and in the middle of the city close to all sights. Due to the very central location, the city is buzzing and may be too loud for light sleepers. It did not bother us at all, however.
We would have wished for a tea towel + dishwashing soap for the kitchen. Everything else was lovely.
