The appartement, on the fifth floor, is very nice and spacious with big comfy beds. The interior is modern and well designed. There is a (small, 2-person), elevator in the building.
The place is situated very central in Athens: major sights are in walking distance. It is also unfortunately situated at one of the busiest roads of athens with lots of traffic day and night. If you keep the well isolated windows closed this is not a problem, but otherwise its very noisy. All the airconditioning units work very well by the way.
The kitchen is simple and could use some more pots and pans, but everything's there.
The apartment was spotless and clean. All the bedlinnen and towels were fresh and clean.
When we were there the toilet was leaking and the washing machine didn't function properly. I'm however sure they will fix this soon.
Would recommend!
