By all means great experience. Great room, splendidly decorated (my girlfriend loved it especially), fantastic and comfortable bed, clean. Enough about a room :)
Anika was great host too, provided us with all necessary infos, etc. Location is also great, peaceful neighborhood, just 3 min walk from the Metro and just 3 stations from the Centre. Since the Berlin public transportation is remarkable, you will only need 10 minutes to the Centre (Alexander Platz) at all times of a day.
So, all in all, fantastic trip :)
