Martin was very quick to communicate with us and made the process very easy. He met us at the apartment on arrival and gave us lots of tips for local nightlife and eateries. Apartment was excellent, very clean and spacious. Martin provided all the basics for a self catering trip: milk, coffee, tea, towels, shower gel etc. Great location for exploring the city, only a couple of minutes walk to two U-Bahn stations and within ten minutes of Berlin centre on public transport. All in all, a great apartment and a great host. Cannot recommend Martin enough.
