Tips suitcase bag for travel up to one week

Hi, I bought this suitcase (rather sturdy bag on wheels) for the trip to Berlin for a week in winter.
Previously, I had a 42 liter volume of purchases. But since I have immediately responded and exchanged for this.
42 liters is probably something for a weekend in the summer. More goes there really is not pure. (Incidentally, this is a review from a man ;-)

I can only report positive after my trip.
The roles are super quiet. So when morning comes out of the house does not get any with the same, that it's going on a trip.
The bag stands on its own and does not tilt to, no matter how full or empty it is.
Very well made.
Telescopic pull-stable.
Material very easy to clean and waterproof.

Especially if one is housed in a hotel like the Motel One, the bag is perfect.
Lie on your chair, zip on and living out of a suitcase.
When it is fully opened you have very good access to the entire content.

The bag / suitcase has a very low weight.
So really convenient for travel.
The next trip for a wet week in Hamburg has also passed with flying colors the suitcase.
And still looks like new.

Would I buy again and again.
The bag / suitcase is perfect for me.
