Fundamentally, all you'd want from a city Airbnb. Modern appliances, clean, comfortable, etc.
Very easy to find, basically just a straight line through the heart of town from Manchester Piccadilly station (and Manchester Victoria is close by, too, if you're coming through there).
Conveniently located with plenty in walking distance. There's a small Tesco very nearby for your essentials, but also the main shopping center a little further into town for more serious shopping.
You've also got the river, cathedral, National Football Museum, Peoples History Museum and plenty else very easy to get to.
Comms with Mark was grand, and overall can certainly recommend.
