Ilias place is everything that is advertised: very central and conveniently located while away from the tourist hordes; full of character and very spacious; and ran by a fabulous host. Ilias was super helpful and flexible before and during our stay, from accommodating our late arrival, helping us with taxis and public transport, suggesting restaurants etc. Koukaki is a nice neighbourhood, right by Filopappou Hill, which we climbed on the first day to approach the Acropolis from a less obvious angle. You can easily walk to nearly all tourist attractions / historical sights, which we did with three young children. There are plenty of good bakeries, cafes, supermarkets, ATMs within a 5 minute walk, with pedestrianised Giorgiou Olimpiou Street a particularly nice spot.
