I just completed a 3 night stay last weekend at the Nordica Hilton. I was very pleased with the hotel and glad that I chose the Hilton Nordica over the Canopy downtown.

The Hilton Nordica is full service hotel, and I was upgraded to a 9th floor Exec Room Queen Plus - large windows facing the water.
I was not bothered by the limited road noise - it is not a freeway per say - so mostly quiet at night - with just a few cars.
Nice lounge and breakfast is server in the restaurant - all very good.
Had a car - so free parking at the hotel. A easy 1 mile drive to the main downtown area - via the road along with water.

Parking downtown was somewhat difficult - any time of the day or night - contrary to what I have read.
Never any parking at the Church lot or surrounding streets in day time or evening.
With some effort I was able to find one space 3-4 blocks north of the Canopy. Paid lots were full.

So if you stay at the Canopy - a car will be a problem - hard to park and street is pay parking in the day, if you can find it. Plus you will get bar noise at the Canopy.

The Noridca Hilton does have a spa - the main area of the spa is old, but they do have a new large sauna and hot tub on the outside patio - from the old spa area - walk through the gym and go outside - and right there. There is no sign indicating the new large, wooden sauna and outside spa.

I would say the Hilton is by far the best place to stay if you want full service hotel - lounge, restaurants, spa, parking, nice rooms, etc. Best to have a car.
