I have stayed in the Hilton Garden Inn twice during business trips and would definitely book this hotel again. It is a modern and clean facility. The rooms are quite big and nicely furnished. The beds are very comfortable but maybe a little too soft for some people. The room has been cleaned well every day. The hotel also offers a small gym area and an indoor pool. Staff was always friendly.
The breakfast is always good with a nice variety of food. They offer some fresh fruit (two kinds of melons, pineapple, apples), sausage, bacon, scrambled eggs, fried potatoes, pancakes/waffles, toast, bagels, several pastries, yoghurt, milk, porridge, cereals and you can also order freshly prepared omelettes or eggs (I hope I didn't forget anything important).
You can get coffee, tee and water at any time for free in the lobby area.
Unfortunately, the last time I got a room with an AC/heating unit that could not be set to a slow fan mode. Therefore the fan was a bit loud and produced quite a strong air flow through the room and towards the bed. I had to switch off the heating before I went to bed.
Other than that my stay was just great.
