Manchester is one of the best walking cities I've been to, and Aaron and Silvina's place was the perfect launching point. All of the 10ish pubs I wanted to visit were within 1-1.5 miles (Lower Turks Head, Gray Horse, and Briton's Protection were my favorites), as was the fantastic Paramount used bookstore, Chetham's Library, and the People's Museum. I typically wore myself out by midday and headed back to the comfortable flat for a nap, a shower, and/or a little Netflix. I was also able to wash a load of laundry and hang it on their rack to dry, which was a huge plus.
The hosts were also super friendly and accommodating: they gave me options for luggage storage (which I ended up not needing because the room was ready for me) and when I discovered they were out of laundry detergent, they overnighted a large box).
Highly recommended.
