If you are looking for style and a bit of a view of Lycabettus Hill, then this place will meet these requirements. However, I was put off from the rather corporate feel that my communication with them had as well as some other issues which I am listing below.
To begin with, within 30 minutes from booking it, and having already received their email with requesting my passport number, I received a phone call from their central offices asking me for it. In that phone call, I asked if I could leave my suitcase in the flat after the check-in (I had a late evening flight) which they said it wasn't possible due to being booked (it wasn't) and offered me to leave them to their central offices in a different district of Athens but with a charge. Of course, it's not obligatory to allow me to leave my suitcases for free, but it would have been a helpful and courteous touch given that I would have to pay for a taxi to reach their central offices in Neos Kosmos.
When I arrived at the entrance of the block of flats where the apartment was based at 3 o'clock on a hot Athenian afternoon, I couldn't open the safety box where the key was kept as they had given me the wrong passcode. After a 15-minute calling back and forth (from my international mobile number and having had to provide pictures of the code I was entering through the app), they did sort it out, and it turned out to be their mistake. The woman I spoke on the phone didn't even have the courtesy to apologise for their mistake.
Once inside, I realised I needed a card to switch on the electricity, something I have only encountered in hotels. The issue with that is that the WiFi needs to reset each time you come in which is not ideal if you, like me, depend on the internet, to work or attend meeting and need to wait for it to come on. Sadly, there was not a bottle of cold water in the fridge which would have been a nice touch especially on a hot summer day (which is something I have encountered in other Airbnbs). The veranda, beautiful though it was, looked dirty with dirty ashtrays still on the table, while the fence was coming off on one side and was in a desperate need of repair. Sadly, the same with the kitchen, the area around the cooker was dirty and the washed dishes dumped onto a dusty shelf which wouldn't have been a problem if they didn't charge a cleaning fee. The towel was worn out and tore apart the third time I used it, while the hairdryer didn't work. I did see the directors of the company who were waiting to come in to clean on my way out of the flat, and raised some of the issues with them. I got a sense of being defensive with some of the negative feedback.
I doubt I will book the same flat again unless some more love and care is put into their communication and maintaining a better cleaning standard.
