The apartment was a great place to stay for my month long trip to Athens. The main location's was in walking distance from all they main attractions and a small walk from the metro.
The apartment was extremely clean and offered most amenities that you'd need for a long stay (although a bin and a set of knifes would have been nice).
The WiFi averaged around 10-15 mb which was sufficient for my tasks and has a small desk that I could work/eat at.
The view's from both balconies offered amazing views of Athens. Whilst I visited in a colder months I imagine they'd be great in the summer.
Kalliopi overall was a great host and offered tons of information about Athens and local places to visit.
I'd happily stay at this apartment again.
