Ibis stuttgart was very easy to find, just look for the sign that says "Ibis Hotel" near the tram that was conveniently just about two minutes away (unfortunately I don't remember the name now). The room was very clean and nice, the staff very helpful and got us food very late after we came back from a concert even though we'd passed the time to serve food. The price is also very good. I can really recommend this hotel unless you aren't looking for a luxury kind of hotel.
