To everybody who's going to spend a couple of nights in the studio: It's amazing! As long as you don't want to roast chicken, there is everything what one usually needs. A comfy bed/sofa, plates, glasses, cutlery, table, chairs, adequate view, lovely bathroom, towels, shower gels, shampoos, soaps, sufficient cabinet in the hall, bunch of paper guides to Berlin, and of course, lots of mirrors!
Jonathan was also so kind that he let us come already in the morning as we had quite heavy luggage. Cheers!
Book it while it's vacant! Absolutely worth it!
