Yupp.. you want to stay near the core or Financial district area. South of College, East of Spadina (actually Bathurst), West to Church Street. Plenty of Airbnbs. Gives you easy access to TTC that is Subway, Streetcars, and uber is cheap. Great for walking around. Consider rooming house type stuff, basements, etc. Plenty of cheap options since you'll be out alot. And yes, alot of incalls so no need to bring anyone over.
