The hotel is located right in the center of the old town. You can walk to the Acropolis and to the main tourist streets. The room had no view (unless you are into air conditioning units then you'll love it). The staff were not very helpful when I asked for help with figuring metro system or charging plugs.
The hotel was right on the subway line which made it perfect to get to the port and airport. (side note - Athens subway 5 stars: Clean, efficient, safe, cheep and easy to figure out. Despite what the staff at this hotel thought even tourists can use it.)
The beds were super comfortable.
Street noise was significant but that is what you get for sleeping dow town so I was ok with that.
Now the thing that gave them the 5th star from me was the breakfast. OMG was it ever good. You have to stay there just got the breakfast spread!!!!
Yeah, give these guys a go, they were good to us.
