Currently here on a 6-night stay, absolutely zero Diamond recognition apart from the breakfast and purple key "envelope". The bed is comfy and room is generally quite pleasant (I could use a bathtub though) but it's a bit disappointing - it's my first Hilton stay since February, having moved most of my business this year to IHG, and this treatment reminded me why
I pre-booked airport transfer with the airport, which came approximately at 30 EUR. Quite a bit above than the market rate for taxis, but still cheap enough for me to prefer it over navigating in a completely new environment at 4 AM after one too many glasses of ouzo from Aegean

I will use normal taxi (GG app) on the way back though.
Location is just perfect, walkable everywhere + lots of public transport options around. I can confirm the cookie is back. The welcome gift mentioned some years ago doesn't seem to exist anymore, and the minibar is no longer stocked.
All in all, not bad but if I'm back, I will likely give Holiday Inn a try the next time.
