Fantastic experience. Toni's team were super responsive in the lead up to the check-in and throughout our stay. The apartment was exactly as shown in the pictures - stylish, modern with very large rooms by Athens standards.
Location cannot be beat as far as proximity to the metro and the downtown core (Monastiraki, Plaka, Acropolis etc all very close by). Neighborhood is a bit iffy at night, although there is a very visible police presence, so at no time did we feel unsafe.
All in all, a great experience at Toni's. Would have absolutely no hesitation in booking this, or any of Toni's apartments again.
