The contact with the Netherlands Isoleert has been very pleasant.
It is unfortunate that the execution went wrong when it turned out that the space under the floor

It was not possible to get to the room under the living room.
It was also annoying that the two very friendly people had to make a vain ride for this.
But who knows. Next time might be better.
