The apartment is quite nice and has basically everything you might need even for a longer stay: full and well-equipped kitchen, dish washer, nice bed, surprisingly spacious shower etc. As other guests already noted, the apartment is quite dark so that you will have to turn on the lights all day (which I did not mind). Aaryn was very responsive and did her best to accommodate my needs.
It should, however, be noted that the apartment is close to the very sketchy neighborhood directly east of Moss park. Since I saw that Aaryn shot down some other reviews mentioning this point by stating that homelessness is normal in a big city like Toronto, I felt the need to be very clear on this: This has nothing to do with living in a big city but is very specific to this particular area.
While the houses on the block itself (including the one with this apartment) are really nice, the area across the next street (Shuter) is a totally different story. Additionally, right around the corner (on Sherbourne) you will find the Maxwell Meighan Centre (homeless shelter), salvation army, and the followers mission resulting in a steady group of homeless people/junkies hanging out on your way to Downtown. In Moss park itself you will also find a lot of homeless people hanging out near the needle disposal boxes. On the other side of the apartment's block (on Dundas) there is Margaret's Drop-In Centre, drawing with the same crowd as on Sherbourne. These are all things that you can google yourself to make up your own mind.
To be fair, these people mostly keep to themselves except for the occasional begging, but if you are sensitive about those things, you might feel unsafe. Personally, I did not mind until one day (6pm, broad daylight) some guy tried to grab my phone right out of my hand literally in front of the Maxwell Meighan Centre. Luckily, he missed and ran away. This has never happened to me anywhere else.
Overall, if you want to stay in this (cheaper) area anyway; if you don't mind these crowds; and/or go by Uber/taxi/car: I recommend the apartment. But I'd also highly recommend to be careful and keep your belongings safely in your pockets.
