We had a 12 hour layover in Athens and are past the point in our lives where we'd consider trying to sleep on an airport bench. We booked a room at Comfort Stay so that we could get a good night's sleep before a long day of travel, and it was a great decision!
Our flight to Athens arrived a little later than expected but they quickly got us on the shuttle and transferred to the hotel. When we arrived, check-in was friendly and quick and we chose our options for breakfast the next day.
The room itself was well beyond what we needed for our quick trip but seemed outfitted well enough to provide a reliable home base for exploring the city. The beds were comfortable, the mini-split heat pump worked well, and we got a great night's sleep.
If you are a light sleeper like me you'll probably want to wear earplugs, there are a number of dogs in the area that like to make their presence heard - but if you're traveling through Europe already that shouldn't be a surprise, and is no fault of the hotel!
We woke up the next morning to breakfast brought to our room, then took advantage of the amazing shower (seriously, it was great!), and then hopped into a taxi back to the airport that the hotel had arranged for us the night before.
Overall it was an extremely efficient stay and perfect for our needs - I would not hesitate to stay here again.
