Location is very good, an area full of bars, coffee shops, restaurants, etc. And you can get to the Oktoberfest by walking 15min approx across really nice places.
The place is fully equipped, you won't miss anything from your home.
Only have in mind that one of the beds is elevated and the space to the ceiling is very short, if all of you are very tall this could be a problem.
Henrike herself was super nice and always available if needed, she also kept our bags when we left the apartment until we had to leave town, so we could walk free :)
Her friend Anita was also super nice!
Both of them are very nice people to talk also, I regret we couldn't talk more.
I would definitively stay there again and I recommend this place to everyone!
