I had a great stay at Amedia Luxury Suites in Graz. My room was quiet and clean, with a nice view of the courtyard below, and the main street heading into Graz.
Breakfast always included fresh cut fruit, yogurts, eggs any style, and fresh breads. As well as coffee and juices.
The staff was always very friendly any time of day, and I was always greeted when I came in for breakfast.
Though located a little out of the way, there is easy access to transit options, there are two groceries stores next door, and there are also nice restaurants less than 1km away and are easy to walk too, I recommend Heinz.
Next time I'm in Graz, I would stay at Amedia Luxury Suites again.
