Don't expect anything from Helga, except her "stop calling me" answers".
However, the estate agent (?) who gave us the keys was pleasant.
The proper flat is ok. For a family, or 2 couples (our case). Well situated (metro, buses..., pretty silent, comfortable.
We didn't like the bathroom/toilets glass doors, not really discreet...
A really good option, despite the Helga's reactions.
