Max's place was fantastic. Checkin was extremely easy, the apartment is located in a wonderful part of Berlin within walking distance of tons of restaurants, parks, markets, night clubs, bars, and U-Bahn/S-Bahn stops to get to museums. The place is perfect for large groups who exercise respectful noise levels. Seriously, that part is no joke, the building has a ton of extremely nice families who will say hi to you and hold doors open for you and even share a cigarette with you every now and then, so if you're looking for a place you can be super loud in late at night, this isn't the spot for you because they need to sleep. And honestly, there's no need to be loud in the apartment that late, JagerKlause and other bars that stay open all night are literally less than 300 meters walk away - we'd just head there after 10pm and head home when we were ready for a sleep.
I would definitely stay here again, it's a fantastic spot!
