The 1st floor of the Poucher House was a nice, cozy place to come back to after exploring Toronto throughout my trip. The Wi-Fi was also plenty fast, making it an excellent place to work, if you are working from home (or just called in to do things). The location is excellent, providing a short walk to busses, streetcars, or the subway - with public transport being available from a short walk in any direction - meaning getting places in the city and coming back is super convenient and easy. Keep your G Maps app handy and you should get everywhere no problem.
John also suggested acitivities that I could go to, which were happening throughout Toronto while I was there. There's plenty to do without a car, and public transport can get you most anywhere within Toronto, but you may want to bring/rent a car if you plan to leave the city to go sightseeing. I was able to pack a month of activities without once needing a car. I quite liked Casa Loma (Vesta Lunch is pretty good, a short walk from the castle), and the Royal Ontario Museum was neat, as was the Toronto Railway Museum! There's also plenty of public parks to get to, I liked reading books at the park occasionally.
The house is split into three units, one per floor, and he lives in one of them, so he's generally available if you need anything. The floors are separated with each entrance to each floor locked, so any stuff left in the unit is safe. I felt comfortable leaving my electronics in the unit just fine. It is like an apartment complex, and not a shared house with separate rooms for rent. Each unit is completely self sufficient.
John is a super nice and caring host, I loved having conversations with him in the mornings. He has a lot of interesting stories to tell! I love to hear about people's different experiences, and he has no shortage of them! He also seems very reasonable, I don't believe anyone should have a problem as long as you treat the house and your neighbours above/below in it with respect.
