Agiro and her partner are really nice, responsive and helpful hosts.
The appartment is nice and calm, in a charming residence. Large and confortable bed! that's a plus when walking all the day ^^
Really clean and well equiped for tourist/short stay traveler (we stayed 4 days, 99% outside the appartment :))
4 stations from Syntagma place and 30 min metro from the Airp.ort.
Taxi cost about 8€ to come back by night (via BEAT application)
That's a good location that I would recommentd!
