Natalia received me at the apartment when I arrived. She was super nice and explained to me a bit of the house rules and showed me around the apartment.
The communication previous to my visit was also really good.
And what to say about the apartment itself! It was lovely! Really clean, in the perfect location, and in perfect condition. It has all you need for a short stay :D
I would totally recommend staying at their apartment if you are visiting Munich :)
