Shared bathroom facilities weren't ideal, but that was the type of room that was left, so that's what I got. It all worked out in the end.
I liked the feel of this hotel. Going into it, I was alerted that my room -- the last one left -- was a 'budget' single room with no bathroom facilities, only a basin sink, and that the bathroom was down the hall. A little unconventional, but no problem. The price wasn't the cheapest, but I needed a place to stay in Munich, and this worked.
I took the train from Nuremberg to Munich and walked to Marienplatz from the station. Looking for the hotel (and thinking I needed to walk much further) I stumbled upon the entrance all-of-a-sudden -- the place is so close to everything you want to see!
The staff were all very kind and helpful, and they let me stow my bags for the day (I got in at 9am, room not ready until the afternoon) and gave me tips as to where to eat and what to do.
The hotel has the feel of an old-time establishment. Heavy metal keys with brass fobs attached open the doors to the rooms, and are left with the reception (who memorizes your name and calls you by it) upon exiting, to be picked up upon re-entry. Something about this is just more refreshing than your run-of-the-mill Marriot.
The following day, I checked out and had about 11 hours to kill before the night train I'd booked to Venice. The staff let me stay later, stored my bags for me, and kept asking if I needed anything -- even in spite of having relinquished being a guest.
Also, and I can't stress this enough: it's dead center of Marienplatz and the Viktualienmarkt, but just out-of-the-way enough to not be noisy or touristy.
Overall, I loved the place and would easily stay there again -- although next time in a room with a toilet!
