I had a great time at Penny's place. It has all you need for a short stay. The neighbourhood is quiet but close to some good spots. The TTC is 10 minutes walk and the UP is less than five. You can be downtown in 20. There's a good grocery store 10 minutes walk away over the tracks. It's a basement space so you can hear the occasional noise from above, but it's very comfortable and has a great seperate entrance.
Penny was lovely and super helpful. Excellent hosting.
