Get a room with a great view as an upgrade - functional and tastefully furnished.
Unfortunately, it is an absolutely subterranean "swimming pool" that only exists so that you can write it down in your description and that could just be sufficient as a cooling pool for the equally small sauna. No real fun even for the small children in the pool. You should give yourself this area for free and actually make the wellness area a wellness area.
The leaky and rusty bottom area of the aquarium is due to unsightly covers of the already uncomfortable hotel bar, so that it does not drip into the drinks ...
On the other hand, the excellent breakfast buffet, which can also be enjoyed in a quiet setting, is very positive, as there is enough space in the restaurant.

So get a nice room with a view of the cathedral and don't go to the wellness area or even the swimming pool, then you won't go wrong.
