Awesome video Maikol! My Mom has a friend who lives in a town on the outskirts of Berlin! Putting Berlin on a bucket list for me & her visit and these spots as must visits. Her and her friend as jazz fanatics!
Berlin is well-known as being the techno capital, but I believe many still need to learn about its incredible melting pot of scenes and cultures - musically speaking. The best time to come and visit the city is May for the XJAZZ festival. It would be fantastic having you here, exploring this magical city.
I will recommend Yorkschlösschen in Kreuzberg. Its a bar with live jazz and blues. There also have some en food and a garden. It is not very big especially the room with the music are small. Reservation is recommended.
