Due to the transit strikes, I arrived late in the evening. Kostas was very helpful at the front desk. The room was great, although I had a room facing a back alley - not really scenic but at least very quiet. The three key elements that I look for in a hotel were met: plenty of hot water, strong wifi signal and good beds. When the wifi signal dropped off a couple of days into my stay, the front desk relocated me on the top floor with a large patio and a nice view of the Acropolis.
The rooms were spacious, clean and up to date.
Breakfast was quite good with meats, cheeses, yogurt and honey, eggs, juice toasts and coffee.
Geographically, the location is good but you must keep your wits about you when walking especially at night in the area. Although the area is well lit, I did witness a purse snatching in the square across the street and drug use is frequent and open. Not to worry though, because the hotel seemed very secure. There is a police station just up the street, but that seems to have little impact.
A 20 minute walk from the hotel, down Athina street takes you to the Acropolis through a very vibrant area.
