We stayed here for one night prior to our departure for home. The hotel is right next door to the Athens Hilton and in a nice part of town. The room and bathroom were adequately spacious and well appointed. Our room had an enormous balcony, more like a patio and big enough to have a party! All in all not too bad, but with a few caveats. The breakfast was extremely limited and not very good. The air conditioning in our room didn't work. The hotel has only one very tiny elevator which can only hold 2 people + 2 bags.
It's about three blocks to the nearest Metro stop, Evangelismos, and taxis are always available just at the end of the property between the Ilisia and the Hilton, so getting around is no problem.
This hotel is not particularly inexpensive and should certainly have done better with its breakfast. There's not much that can be done about the elevator and you can work around its limitations. The air conditioning is repairable, but in Athens at a hotel that claims to be a four-star I expect a high standard of maintenance. The staff at the front desk was most pleasant and helpful.
If you want to be in this part of the city it's not a bad hotel, but there are equally good hotels for less money in what may be less desirable neighbourhoods.

Not the best first impression I guess. My husband and I had such high expectation to visit Athens, but we were really disappointed.
This hotel was a gloomy, and it there was always just one person who was not even able to help we everything we need.
The room had some kind of smell, not romantic at all.
It was difficult to find food, but here is a tip : weekend nights if you are hungry, walk out of the hotel to the left and go about 100 meters, there is a sausage food truck. The front desk man was not helpful at all.
No internet in the room which is inconvenient.
I couldn't stand it the second day so I made my husband take us to Mykonos two days earlier than scheduled.

Small and noisy rooms, simple atmosphere.
If you expect to have a breakfast like in a normal 4 star hotel, you will be totally disappointed. The breakfast at that hotel includes only 2 types of ham, 2 of cheese, bread, butter, jam and compote. No fresh vegetables, no fresh fruits.
I think that 2 stars will be more than enough to this hotel !

My view, like many others that I have read, is that we only have negative reviews on this hotel. The room was dark, dingy and in a very poor condition. I would certainly never recommend it and it is hard to believe that it has been graded as 4*star!!!
