For a budget hotel, it ticks all of the boxes. A swish foyer with helpful staff and a large and reasonably priced bar. The rooms are modern and clean, though as you would expect for a budget hotel, not huge. Breakfast is excellent for the price.
The location is also very good, just a few S-Bahn stops from the airport, a short walk from the main rail station and well connected to the city.
It's difficult to find drawbacks, though the place is clearly very new and I wonder how well it will age.
