I have written this on another post. Should I repeat this ? Here goes:
My overall experience with your residence was very positive. The staff are very helpful, the room facilities are perfect, the residence is equipped with every amenity required for either a short or long stay, the furnishings and equipment are very well placed and fitted - in short, I shall definitely return to SANA Berlin when I visit Berlin next. Other features: The U-Bahn station is just a 3 minute walk.
