It’s not bad.
The rooms are quite tight, hard to walk to the other side of the bed without hitting the TV. The shower glass is way small to prevent spill, but if it was the right size, raising your arms while showering would probably be painful. The huge unstable drain right under your feet makes it even harder to shower.
Because they did not open an account upon check in I was unable to charge to my room the water I consumed by the pool (no umbrellas) since I went there without a credit card. Then I forgot to go back and pay, so in a few hours time when I was out they called me on my cell to ask that I come to the reception asap to pay the €6 that I owe them. That was 2 days before our checkout.
Breakfast is not bad but the restaurant manager was the nicest guy I have met in all Athens.
You can not go directly to the parking lot. You have to go out, walk 200m and take another elevator quite inconvenient with kids and beach bags. I highly recommend to park on the side street, for free.
