The flat is at the basement level (-1) which was not clear from the photos but has its own very nice terrace. It is centrally located, well equipped and well constructed with tasteful furniture and art.
It is slightly on the expensive side in the Athenian range but worth it if you are looking for a quality stay in the center.
In the winter months it could use some better lighting and central heating but I can imagine that in the Summer its perfectly nice and cool. The terrace was great as well and I would love to enjoy it on a Summer stay !
The host was impressively communicative with fast response time even late in the evening! Thank you for that!
Overall would recommend a stay in this flat.
