The apartment was big and cosy. Very close to the Syntagma square and very close to all main attractions. The beds were very comfortable and the rooms were equipped with towels, shampoo/shower gels, iron (since we were there for business, this was very important for js :)) ).
It was clean and airy.
The hosts were very helpful and very fast responding. I would definitely suggest this apartment to anyone visiting Athens either for business or pleasure!
