I believe this was the former Crown Plaza, which I stayed at a few times. The rooms were nice. The building was re-purposed into a hotel. So, the architecture is somewhat unique. It's only a couple of blocks from a tram stop. And it's next to a "back entrance" into the park which overlooks the city from the west (the one with that mini-Eiffel Tower on top).

Also another thing to note, these hotels are offering 500 bonus points (new hotels) per night through late September. And according to those T&Cs, these apply to award stays as well. Not as good as the 2K per night award stays (after the 3K rebates) I had during the springtime promo. But almost as good.
