Alex’s place is super sweet and comfortable, our room is big and stylish, we had very good sleep there. He is a very open and well communicate guy, he gave us a lots of good advice. If you like east Berlin culture Alex’s place is perfect, very easy access to the clubs around, and a good chill skate park. And just go downstairs, there are many good restaurants on both side of the street.
Definitely want to visit him again for Berghain.
