First of all Martin is super nice, funny and cool. The apartment is literally 5 minute walk from Potsdamer Platz. Walking distance from every attraction Berlin has to offer. The apartment is was clean, with milk, coffee, tea, some water, and 4 different types of soap to shower. Martin even came out of his way to the apartment when we had trouble locking the door (which was confusing at first). I would differently stay in Martin’s apartment again.
