Thor greeted me with a smile even before the cab had come to a complete stop. He is a very attentive host, clearly wanting his guests to feel at home in the apartment - and to enjoy Berlin. The place is every bit as good as it looks in the pictures; very spacious, clean and newly renovated. I was told to help myself to anything I'd like in the fridge, and it was very clear that this was more than a manner of speech.
The bedroom is quite large with a double bed and blinds that work well to shut out light and whatever noise may be on the street. I slept very well. Guests have a separate bathroom with shower and lovely, soft and thick towels.
Thor also introduced me to several of his friends, and they all participated in making my stay in Berlin a very enjoyable experience.
Kreuzberg is a wonderful area with a relaxed athmosphere. Public transport is easily accessible, and there are several sights worth seeing within walking distance - such as the Jewish museum and Bergmannstrasse.
I know where I'd like to stay if I return to Berlin again in the not too distant future!
