Nasos place is perfect for a city trip to Athens and for a local experience.
Anything you might need while you are staying there is conveniently close and reachable by foot.
Also most of the touristic attractions of the city are just a short walk away.
As Athens apparently has quite high humidity, the place has a bit of mold which seems to be quite common in the area. However, as it is a Mediterranean city, it is easy to open the windows and the door to the terrace and let the air flow.
Nasos is very helpful. I had an issue with the hot water one day and he immediately helped me.
I would stay there again, especially as the area is central but still quiet enough for a good nights sleep.
Thank you!
