I live in number 83, so I know the information I entered was correct :-) The numbering in this apartment block is very confusing.  The outline of the buildings is still incorrect at the moment. I don't know how to fix it (indeed it's my first day), so perhaps you can help me?

Basically, the streetside consists of two blocks (separated nicely in the middle) number 67 and 83. These blocks extend about 8m to the back, forming a small U. The rest of the big U consists of 4 separate houses, 2 on each side. They are numbered 69A, 69B on the north side and 81A, 81B on the south side (A is closest to the street). The building all the way in the back consists of 5 houses, numbered (from right to left) 71, 73, 75, 77, 79. All of these are accessed through the same entrance, in the middle of the 67-83 building. Finally, the apartment in the southernmost corner on the ground floor has a door on the street side and therefore has a separate number: 83A.

I don't know how this should be represented on the map. Everything from number 65 to 85 is in fact a single building. Number 65 might still be separable, but number 85 and 83 are somewhat mixed together on different floors. I think the current outlines are based on satellite images, but the way the roofs are laid out does not really correspond with how the underlying buildings are organised in apartments and houses.
