We know this place quite well since we've rented it several times over the past few years.
The location is amazing -- only a few minutes stroll to most of the major sites of Athens (e.g., the Ancient Agora and Temple of Hephaiston, the Acropolis, Pnyx Hill and Ares Rock, Keramikos, etc.) and most of the trendy, fun neighborhoods of Athens...Gazi, Metaxourgeio, Monastiraki, Psyrri, St. Irene -- and, at the same time, on a quiet residential street.
The house itself was perfect for our group -- plenty of space to spread out, nicely and brightly furnished, clean and tidy. The 3 bathrooms was especially appreciated given that there were 8 in our group this time!
We will be back!
