Excellent place in the Northern Quarter. Arndale and pretty much the whole city center of Manchester was accessible. You have to communicate with a management agency but they're pretty responsive. Also, they don't ask for a deposit which was different from our experiences in Birmingham and London, another plus.
The kitchen is very well-stocked and they provide you with access to any extra stuff that you may need. It is up about three flights of stairs, but there's chairs at every level if you need to take a break. We were worried about slugging three big bags upstairs, but if you've got a couple of fit people you can pull it off. The corridor can be a little dark though and the light switches don't always work.
There's even a little balcony attached to the living room. The two bathrooms are clean and well-maintained too, just can be a little slippery. Overall, a great experience!
