It was a cool location to stay and a nice thing to have the kitchen and everything of a classic AirBnB and the service of a hotel.
Yet, it was a bit awkward, that we found hair in our bed when we arrived. Asked them to redo it.
Afterwards it was a little cleaner, yet not clean. To be safe, you might bring a sleeping bag.
Wouldn't recommend it for your honeymoon but it's good to stay in Munich in a good location, with your own kitchen and space.
