I stayed in Andrew's room for 2,5 months during an internship in Toronto and I think it was the perfect decision: The house is located in a nice, calm and cozy street with lots of trees in Cabbagetown. You can reach many spots in Toronto by foot (e.g. it just takes about 20 minutes to downtown) which is really comfortable. You will also find everything you need (shops, restaurants, pubs, cafes, parks) right next to you.
The house itself is very bright and tastefully furnished. There is a nice patio downstairs for warm summer days and Andrew will certainly invite you for a delicious bbq if time and wheather allow it. The room is clean, cozy and offers enough space for a lot of clothes. It also has an own deck with a small table and chairs.
If you really want to get to know Toronto and its hidden gems, Andrew is the perfect person for that. He is very helpful and likes to show you his favourite spots in the city. However, he never imposes something on you but gives you as much privacy as you need. Andrew always makes you feel welcome in his place so that it really feels like a home far away from home.
Overall, I totally recommend staying at Andrew's house, especially if you are looking for a long term accomodation in Toronto. It's a perfect combination of privacy and great hospitality in a nice area which you will hardly find somewhere else!
