Not impressed, 2/5
The stay was not a pleasant one. Parking wasn't included in the hotel fee's and it was $55 per night or $35 at another location, my room was sold despite me booking it 4 months in advance, I was asked to wait 30 minutes while someone cleaned my room (despite check out being 3pm and we checked in at 9pm, plenty of time) to which I did and nobody ever showed up and cleaned it (we waited 1h before calling to ask what's going on), I wasn't told about the upfront deposit fee until I had arrived at the hotel (which would have been nice so I could have budgeted out some more money as I do not carry more US currency than what I need), and there were police sirens being heard from 11pm to at least 2am when I fell asleep. I received a complimentary free breakfast where the food is mass produced, the muffins were very dry to the point of crumbling apart, the eggs were bland, and even the syrup was tasteless... I'm not sure how you can mess up this bad. They say there was WiFi but we were told we would need to pay, which was true. For $300 CAD I would expect better. Unfortunately this was the least memorable experience for us during our 10 day stay, and we will be looking for other hotels in the future.

Exceptional 10.0
I left my heart at the Hilton Union Square.
Really first rate experience in the hotel. Large room and bathroom. Clean as could be and very quiet. However too many homeless in the immediate neighbourhood with some litter on streets,

Very poor, dirty and tired.
I stay at this hotel every year, this year was really disappointing. The room was dirty, furniture a bit tired too. It looked like someone had a food fight in the room and not recently either, there was old food splatter on the wall and not just one wall, every wall. Dried on weeks or even months ago, grim. I asked the maid to clean it on Tuesday morning, it wasn't done, I asked the front desk to clean it on Wednesday morning, the guy on the Hilton Honours desk said it would be done right away, I went out, expecting it to be done, it wasn't, I complained on Wednesday evening, when I got back, they assured me it would be done on Thursday, I went out, my room was serviced, it wasn't done, I called the manager 'DJ', he said it would be done on Friday. It WAS done on Friday, but really, how many times do you have to ask for old food to be cleaned off the walls before it is, I can tell you, 4 times. Oh, if you use the coffee machine in the room, don't expect the maid to refresh the things you use, like the stirring sticks and creamer pots. Nearly $600 a night, this is very very poor indeed. Very poor. My 8 years of staying here is at an end. Rubbish. Oh there was also an issue with check out and the bill, which saw me wasting more time sorting something else out, that I was told would just be sorted out and wasn't.

Avoid this hotel
Do not stay here. Over priced, run down, terrible staff and a bad neighbourhood. I had to stay here for work and will never do it again. The hotel is run down, it was loud and the halways were filthy. The staff is grumpy, the check in line was beyond ridiculous and the neighbourhood is dangerous (they put security guards on all the doors - you cannot safely go out for a walk). Do not stay here, there are so many better options.
