First and foremost the location is excellent, genuinely couldn't be better positioned to explore Central Manchester and the Northern Quarter. It's a large property as well.
Things to note that I didn't expect: It's fully 3 separate flats inside one property (not a problem at all, just worth noting), the downstairs sofas are knackered (sofa beds mean they collapse when you sit on one of them) and the extractor fan in the ground floor barely works. Also you can't open windows (certainly on the ground floor) and the property did have a bit of a smell when we arrived.
Overall: great location, good for big groups, but not quite as luxurious as the pictures. Would still recommend!
