We highly recommend this apartment!
Location - few minutes to all main attractions or metro. Also apartment is next to a market where you can buy fresh fruits or veggies.
Apartment - is beautiful and has all amenities which you could need (kitchen, laundry, very nice bathroom supplies). Also super cool balcony.
Communication - quick, helpful, pleasant. We have minor issues with iron and it was solved super quickly :)
All in all, if I will come to Athens again, I will definitely try to catch this apartment and stay there and I truly recommend you to do the same!💙
