The room had a nice size. The staff was busy, but very friendly and serviceminded. There was a kettel and coffee and tee to disposal, as well as a hairdryer. The bed was a little to hard for me, another person would prefer this.
The hotel is very near an U-bahn ( Statsbibliotek) and Stuttgart Hauptbahnhof is about 500m from the hotel. From airport, take the U6 to the stop, Statsbibliotek, it´s very easy. There is a ticketautomat, at the U-Bahn station right near to the airport. The trip takes about 35 minutes and costs ca. 3.5 Euro.. Instead of taking a taxi you will see more of Stuttgart, and meet the people there.
The Breakfast for 25 Euro is too expensive if you only drink a cop of coffe, and eat a piece of bread, and some musli. Therefore I didn´t try the breakfast.
