Please take the Intercity Express (ICE) to Erfurt. From there, you can easily take connections of about 15 minutes duration to Weimar Hbf, e.g. the RB20 (dir. Naumburg), RB 21 (dir. Gera), RE16 (dir. Weißenfels), RE1 (dir. Gera) or RE3 (dir. Jena). Moving on, you can walk through the city centre or take the bus No. 1 until you reach the stop "Weimar, Falkenburg" (also about 15 minutes). Now walk back only a few metres and there you are: at the Leonardo Hotel Weimar (Belvederer Allee 25, 99425 Weimar)!
