I spent 2 nights in Herodion Hotel , and was just perfect. The location can not be better, You can find within walking distance most of the historical sights and the museums You should see in Athens. The staff was polite and helpful, they do a great job, quick, considerate. Why I really choosed this hotel, was the roof terrace , and I have to say, was a good decision: the roof terraces with the spa facilities are priceless, the view from the two top floors is more than amazing. After some business meetings, was relaxing with a drink or a coffee
The room was tiny, but nice, and I have to admit, my bed was extremly comfortable.
Would strongly reccommend for business or city travellers as well.
