To sum it up: totally clean, bright, homey place, cool neighborhood (not killed by hipsters).
Philipp is a very communicative host, who was totally flexible with our early check-in and late check-out. Of course in our particular case, it seemed to match with his schedule; still we consider it a very hospitable gesture from his side.
He even allowed us to use his two old bikes. Okay, not very comfortable ones, and bring your own lights, just in case. But we appreciated this free bonus nonetheless!
I would surely come back and climb those 86 steps up to the apartment with joy!
