Great location, one minute walk to the Neos Kosmos metro station (2 stops to Acropoli, 1 more to Syntagma) as well as to a grocery store, restaurants, bars, bakery, and other stores in the area. The apartment was also nice and clean. The only issue we had was the hot water unfortunately stopped working on the last night. It was too late to contact the host, so we didn't inform her of the problem until next morning after checking out. Nonetheless, I'm sure it's been fixed by now so I would still recommend this apartment.
PS: If you struggle to open the apartment door, make sure to pull it towards you when trying to unlock it with the smaller key.
