I'm from Calgary, but moved away a few years ago. I recently stayed here for about a week and a half on business. I was in a Signature King room. The property is beautiful. Nice and modern, very clean, and the staff are incredibly helpful as soon as you walk in. They've got a nice bar in the lobby, though I didn't get a chance to take advantage of it. They also have an amazing restaurant, Charcut, attached to the hotel; you won't be disappointed. Their breakfast was great (prepared by Charcut). Good selection of foods, and they'll provide a box if you need to just take some food to go.
TIP: If you're taking off before 6:30am (when breakfast starts), call them the night before and ask if you could have a breakfast box prepared to grab on your way out.
As for the rooms, they are clean, comfortable, look great, and have the amenities you need. The desk has plenty of room for you to get your work done, even if you have a bunch of documents/books you need to spread out around you.
Finally, the location is excellent. You're just on the south part of downtown, across from the Calgary Tower. You're a block off of Stephen Ave (8th Ave) where there are a bunch of bars and restaurants. You can hop on the C-Train down on 7th Ave and be in Kensington within 10 minutes, or go the other way to the Stampede Ground or Casino. Or if you want to go for a nice walk, head north to Prince's Island Park. Heading south, you go under the train tracks and will find more bars and restaurants. Overall, you won't be bored, and you don't have to go far for variety if you don't want.
I will definitely be coming back to the Le Germain.
