We were five guests staying at Philipp's and Lotte's apartment and it was a delight! It was clean, stylish and had everything we needed to have a good stay!
My only remarks are loud neighbours and slow wifi, but it hardly effected our stay! With the U-bahn station about 10 minutes walk away it never took us long to get anywhere in Berlin and the neighbourhood had lots of bars and restaurants with vegan food, some of it in the same block as the apartment! Perfect for that last glas of wine before bed!
We would easilly stay with Philipp and Charlotte again, and we gladly recommend it to other guests!
