Standard car - efficient and friendly service - expensive

We feel Authentik and/or National could have provided better directions to reach the rental location in Downtown Toronto.
The address leads to a building entrance, yet the rental office is a 10 minute walk away in another building at level -2 / National doesn't appear on signage - and in fact, there is no signage
We waited close to an hour in a parking lot. There are no chairs or nowhere clean to place the luggage while waiting.
Cars are driven inches away from people waiting.
The whole experience could be avoided with some warning and clearer directions from the agency and the car rental company
