The place is good for tourism in Berlin, close to a tube station (a very shabby one with a lot of drunkyards, not dangerous but definitely not nice with kids) buses and trams. Mitte is a very big area with different atmospheres.
The apartment is ok, good views and nice, coffee and tea for the week as well as salt and pepper. You also get Netflix what is fine for the kids.
They have to address a couple of issues in cleaning not bad but need to be checked prolerly (dust in the cups shelves f.i.) and the cooker needs closer cleaning too.
This is probably sheerly incidental but it was hot in August (we are from Cordoba and get 45 in our summer) big windows, nice early morning sun but it can get warm there, no air conditioning, we never thought we might miss it to be honest.
