The place is easy to find. it's just 5mins walk from a metro station and actually super convenient if u travel by metro. But ofc it's not in the center, and there's not much relaxing night life, like traditional shops or cafes, around it, so that you may feel unsafe if you like to stay out late. For me, as I usually go back early and get up early, it's not a problem.
The view on the balcony to the Acropolis is amazing. Hot water works well. A slight downside is that the sheets and bedding are a little dusty. And there is some smoke smell in the bathroom.
Kostas is friendly and is willing to help you whenever he is online. (During my stay, he didn't live there)
Generally, my stay is joyful, and I would recommend this place to anyone looking for good value for money.
