Here are the pros and cons after our weekend at Andrew's place (six adults, one baby):
Pros include...
Value. This place is way cheaper than hotels in the area.
Location. If you aren't afraid of walking, every single neighborhood you'll want to visit in Toronto is accessible by foot from this apartment. It's surrounded by plenty of restaurants, coffee shops and convenience stores.
Space. This apartment is big, with two bathrooms and three spacious bedrooms.
A responsive host. Andrew was highly responsive, answered all of our questions, and gave clear instructions for check-in
Parking. Andrew was able to provide parking for two cars in the city, which is no small feat.
Cons include...
Cleanliness. This is a run down apartment in a run down building. The stairs going up to the apartment were filthy and the walls have clearly not been painted in years. The apartment itself is cleaner, but there is noticeable water damage in the main living area, scuffs all over the walls, and mold in some of the showers / shower curtains. There were stains on some of the sheets. The towels were old and at least one of them had a significant tear down the middle. The refrigerator and freezer had not been cleaned out.
Summary: This was a fine solution for an affordable weekend in Toronto, but it was less than comfortable for the reasons listed above. If those issues don't bother you, you'll love the location and Andrew is a very responsive host. But if you can find an alternative option for a similar price and are less than enthusiastic about what is described above, consider looking elsewhere.
