We had a lovely 8 day stay at this apartment in June 2017. As someone who was born and raised in Athens but now lives abroad, I had a better appreciation of the location of this apartment than the average traveler. The location is perfect, right in the heart of the city. You can easily walk to Syntagma square, Ermou street, Plaka, etc. The wrap-around balcony is really nice and the interior of the apartment is very nicely renovated. Modern and clean design, functional layout. However, be warned that the elevator in the building is very old and incredibly small - it barely fits 2 people at a time. But that is by no means a deal-breaker.
The hosts are really nice and friendly people - very well connected and eager to help. For example, we accidentally locked ourselves out of the apartment one day and they hurried to help us, not once complaining or making us feel bad about it. The hosts mother, who lives in the building, even stopped by and brought us breakfast one day, and she went out of her way to help me book an appointment to get my hair done for a formal event on a day the salons in the area were closed.
We can't wait to go back.
