We really enjoyed our stay in Arne's apartment which was an ideal base for our week's holiday in Berlin. It's in a nice quiet area overlooking a park and with a choice of U-Bahn stations within 6 or 7 minutes walk for easy access to the city centre. Arne was very hospitable and the apartment had a very comfortable double bed, great central heating and wifi and a newly fitted bathroom. There are many good restaurants within a 10 minute walk. We enjoyed the challenge of taking the stairs every day (there is no lift as he points out). Highly recommended unless you don't like stairs.
