Wow, this apartment is so well placed (shopping mall, groceries, various restaurants and fast "Berliner" food at less than 5 min, an underground garage if you drive to Berlin, U & S bahn Frankfurter Allee at less than 5 minutes, everything that you want to visit is less than 30 min by transport public - Alexanderplatz, Postdamer platz, East Side Gallery, etc.) and so well equipped (beyond the quite rare sauna in such a big city, Bernd is leaving us a place to live in with all the equipment that you would love to have in your house - you indeed live in his house).
To finish this good impression, Bernd is such a great host, greeting you personally to provide you with help and putting some personal touches to welcome you in his house. You feel genuinely welcome!
All of this leaves you such a great memory of a stay in Berlin!
