This is a solid 5-star unit, hands down.
It's convenient. I walked to Oktoberfest within 5 minutes. My friends who needed to take the train home after Oktoberfest had to walk farther to get to the train station than I had to walk back home from the festival.
It's quiet. Even though it's close to Oktoberfest and it's noisy out at night during the festival, the unit is pretty well-isolated from street noise. I was amazed that I could leave my window open and had a call with a friend and he didn't hear anything in the background over the phone.
It's clean. Everything was just spotless. Don't need to say much here.
Mustafa is super on top of things. He reached out 2 days prior and offered for late check-out as well. He just stayed in communication the whole time and I can't ask for a better host.
I would totally get Mustafa's unit when I come to another Oktoberfest in the future.
