Robert was an excellent host, and I only wish we could have stayed longer. We took an overnight flight from the US to Berlin, and Robert let us drop our bags off early in his flat before the previous guests had left the flat we were to stay in. He offered us maps and suggestions for what to do in our one day in Berlin, and we couldn't have felt more at home. The heated waterbed and the heated bathroom floors were major bonuses! I would highly recommend Robert's place for anyone visiting Berlin!
