My sister and I were made very welcome by Mete who communicated with us before we got there and his lovely girlfriend, Anna, who let us leave our enormous suitcase at the flat miles before check-in time. They'd even prepared us a veggie/vegan guide to Mitte complete with maps and descriptions which we used religiously over our 4 day stay. The location of this flat is exceptional, the huge balcony looking out over a park soon became our favourite place in Berlin to retreat to at the end of an exhausting day. Mitte is full of cafes and bars, directly on the river and close by public transport. I can't recommend these hosts enough. It was our first trip to Berlin and my first Airbnb experience. It's one I'll never forget.
