My partner and I stayed at 1A twice; the first was for a span of a week and later, an overnight stay (en route to Amsterdam). The first stay was in Room 4, a spacious room with medium sized bathroom. It was cleaned everyday and quiet - very ideal. The overnight stay was in Room 9; it was more spacious than Room 4 but the bathroom was smaller. Room 9 was also a little more noisy as the room was facing the street but it didn't bother us too much.
Overall I found 1A Apartment to be great value for money. Ralph, the person in charge, was helpful when needed and mostly left us on our own - which was an ideal arrangement for me personally. Location of 1A was great; 5 minutes walk from Shoenhauser Allee station with lots of shops and restaurants all around. Convenient.
