A great place not to be overlooked!
We stayed here for one night for a hen do and it was absolutely perfect for what we needed.
The location is great for the attractions of the Northern Quarter and although there's a bar on the ground floor (the flat is on the 3rd) earplugs were provided in case the noise disturbed anyone which I though was a thoughtful touch. There's some great bars and restaurants locally just a coupl of minutes walk away.
The flat is simply decorated but was clean, bright and comfortable. The beds were comfy and rooms a good size; for a short stay it didn't feel overcrowded with 5 people. I thought the kitchen was well equipped and liked that items like teabags and miniature toothpastes were provided. The only downside was the shower (an electric one) which felt pretty feeble (still enough pressure to wash your hair though). You should note that the flat is on the 3rd floor and there's no lift.
Communication throughout was good.
Check in was easy with doors all key-coded.
It's not flashy but does represent great value for what you get.
I'd not hesitate to stay again next time I visit Manchester under similar circumstances.
