The appartment is great. Spacious and in modern IKEA style it has everything you need and more (king size bed AND 2 sofas, 2 powerfull AC...) Location? You are literally in the heart of Athens in a lively street with central metro station of 2 lines crossing and Athen's main square Synthagma or the National historical musem only 5 minutes' walk away!
Emmanouil is also great, very attentive, empathetic host, he answers in few minutes and self-check-in is smooth although you need 4 keys to enter the appartment. Only backdrop is that the 2 wonderfully kept-in-tact old big windows are oriented towards a small interhouse yard - there is no nice view from the appartment and on the ground floor is a bar that turns into a club on weekends (but Emmanouil provides you with orthopax in case you rather sleep than join the party ;-)
