The appartment is very nice and just like the pictures.
We had no issues at all with the traffic nearby but very "traffic noise sensitive" people might.
The location is perfect for exploring Athens, with everything being easily reachable by foot.
The Internet seemed to have slight issues with more than two devices being connected, not suitable for a reliable remote work but no issue at all for a regular holiday.
The bed, pillows and blankets were really nice and we enjoyed our stay a lot.
