Location-wise, Erin's place is perfect. The CN-tower is literally right around the corner and the Union metro and train station are only 1 minute away. If you want to be in the beating heart of Toronto, you cound not have a better place to stay at. (And since you're at the 15th floor, the view is A-MA-ZING).
Unfortunately, this great location comes with a lot of traffic noise, which you can hear all nigt and all day long. Personally it didn't really bother me, but it's something you might have to keep in mind.
Erin was a great host, she was very friendly and gave clear instructions about how to reach her place. She also left free water and chocolates in the room 😉
The room had a private bathroom attached, which gave us the privacy we needed. This was however not a private appartement, so you could sometimes hear her conversations with other people in the other room or the sound of the television.
We loved our stay here and would recommend it!
