Highly recommended, very clean, best location just 2 steps from Syntagma Square, very safe and quiet! You can reach out in 10 min by foot Plaka, Monastiraki square where you can find some nice rooftop bars with Acropolis view, also Acropolis is really close. Just next to it there is Ermou street, famous for shopping, you can find everything there.
Don't miss Krinos, 8 min away by foot, you can eat there best loukoumades in Athens.
Georgina is so kind and available, my next time in Athens will be back for sure 😀
