We travel a lot (and all over the world). One of the very best hotels we've stayed in.
PROS: excellent location; VERY walkable to old-town but quieter at night/away from the crowds; close to public transit if you need it; nearby rivers offer beautiful running/walking routes; the accommodations are clean, updated, Bavarian chic and very comfortable; staff was exceptional; dining options nearby are wonderful (in a foody part of the city) - the restaurant/Biergarten attached to the hotel was the best meal and beer we had in Germany (and we had a number of great meals and beer).
CONS: many of the rooms (including the one we stayed in) face a moderately busy street, which could be noisy for some if they need the windows open during warmer months (we live in downtown Chicago, so are used to the noise).
FYIs/Reality Check for Visitors: they don't have air conditioning; much of the EU doesn't. If you're travelling to the EU for the first time and think you'll require a room with A/C, be sure to research your hotel carefully beforehand (would recommend calling and confirming as well). They did have a very capable fan in our room but we didn't need it given the time of year we were visiting.
LOVED our stay here. Can't imagine us staying anywhere else if we ever visit Munich again.
