We stayed in the Athens Hilton twice while on our honeymoon. We arrived the first time at 315am after 26 hours of travel. The front desk staff were extremely friendly, understanding & helpful. We told them that we needed to take a bus in a few hours back to the airport, & they searched online for a bus schedule for us & printed it out before sending us to our BEAUTIFUL room.
We stayed on the Executive floor with a view of the city. The room was spotless & tastefully furnished - very modern. The bathroom was marble & had a glass wall into the room.
Breakfast options were extensive & delicious. The Nespresso machine was a little confusing, but hotel staff quickly offered assistance. I asked for a table to be set outside, & by the time I had chosen my breakfast the table was set, complete with fresh flowers.
The pool is huge, with dozens of lawn chairs around it. Although the pool was very busy when we swam there (due to the 36 degree weather), its size helped to make it feel less crowded.
Overall, the Hilton is an expensive hotel but worth every penny. I would definitely stay there again. There was nothing more they could have done to make us feel more welcome or catered to.
