Apartment was great, accommodated six of us no problem.
The place was pretty clean and had plenty of supplies to keep it that way, the kitchen had some basic equipment to get by, nothing fancy though but that's not really a problem for shorter stays as mine was.
Location wise it's really good, there's supermarkets really close by and the closest rail station is only a ten minute walk next to which is a mall and several restaurants.
Check-in and Check-out were very simple, just walk up to the box, put in the code and retrieve the key. That's all there is to it, no hassle no nothing.
Not much else to say really, what you see on the advertisement is what you get. Would recommend for anyone in bigger groups that'd like to do a city trip to Munich.
