Just finished an unimpressive two nights here, although some of my perspective may be colored by my mostly US based stay patterns.
Booked for three people (king plus roll away) and the "roll away" turned out to just be a sheet and short duvet thown over a very short cheze lounge. My 15 year old was about a 1/2 meeter too tall for this setup.
Room cleanliness was not great on arrival, several items were left under the bed from the last guests.
Breakfast, while extensive, was pretty low quality
Finally the wifi was unreliable and, when working, slow.
Despite that the location is very good and I loved Munich but I'll probably try the city property next time.
