Thor's apartment is exactly as described in the ad and even better looking than on the pictures: it is large, clean, with lots of natural light and even comes with a private bathroom (with a nice shower) for the guests! Sadly I didn't have the chance to meet Thor himself, as he was away in Norway, but I can nevertheless say that his housemate Johnny is definitely an awesome host! He is really accomodating and welcoming, pretty much always available (he works only a few steps away from the apartment) and very generous! He showed me his lovely neighborhood (Bergmanstraße and the surroundings), took me out for a few beers and gave me tons of advice for good places to go nearby (restaurants, bars, clubs, etc). I definitely had a great time on Solmstraße and would totally go back there if I have the opportunity to come back to Berlin in the near future! Highly recommended! :)
