Johns apartment was perfect for our two night stay. One thing I would say is the kitchen could do with some more utensils and a bin, but we managed okay.
John was fairly unreachable as he was on holiday, his brother Dan checked us in fine with no troubles.
The apartment is at the basement on a very busy road, so it was a little noisy but nothing major. Location is about a 10 minute walk into the centre and to the train station which was convenient.
I wouldn't hesitate to book here if I was visiting Manchester again.
