I attended Transport Logistic at Messe Munich and selected this hotel as it wasn't priced the same as a one way ticket to the moon!
The location next to Fassanengarten station is ideal, I travelled quickly and easily to the fair each day for only €3.70 via S3 to Giesing (one stop) then U2 to Messestand West (eight stops).
Hotel was clean, tidy, well appointed and the room offered a fantastic shower, free WiFi, place to work and a free beer everyday you didn't need the attention of a chambermaid - I'm very easily bought!
Highly recommend for good value accommodation, but, be aware that there is no restaurant on site so eat before arrival, reception very helpful and assisted with a Take Away delivery to the room.
