Absolutely lovely property, clean, nicely appointed.
The private rooftop was a great bonus with stunning views, but you can see the Acropolis from several places in the apartment (including the upstairs double bedroom right from the bed) without having to go up to the rooftop. Note, however, that there is a narrow winding staircase to get up to the roof so it might not be accessible for everyone.
The apartment came with all of the basics for a comfortable stay, including a few small bathroom amenities and a fully loaded kitchen (pots, pants, plates, cutlery, dishwashing liquid, etc).
The beds were very comfortable - we spotted a Coco-Mat tag amongst the bed linen, which is a very nice Greek bed/bedding brand.
The apartment had both radiator heating and several AC units so it would be comfortable any time of year. Also there was no button required to turn on the hot water, which was a pleasant surprise for Greece.
The hosts were very responsive and helpful over messaging.
