I was very satisfied with my stay in Trinity's adorable flat! The location is unbeatable—right at the edge of the hip and bustling Northern Quarter, with some incredible restaurants, cafes, and shopping right at your doorstep. (I HIGHLY recommend sampling the different restaurants at Mackie Mayor, right next door.)
Prospective guests should note that the check-in process is a bit involved. You will need to navigate first to a convenience store at an entirely separate address about 1.5 blocks away, across a wide/busy street. I managed fine with my 1 roller bag, but you may struggle if you have a lot of luggage and if it's evening and/or raining (it IS Manchester). Trinity is very clear about this *after* booking and sends incredibly detailed instructions/directions, but you should know this before booking in case convenience/accessibility are important factors to you.
The flat itself is clean, comfortable, and exactly as pictured. I greatly appreciated the presence of a clothes washer/dryer and dishwasher in the flat (laundry detergent was provided, but not dishwasher detergent). The linens were clean and cozy, and plenty of towels were provided in the bathroom. The flat is a bit cold, and the radiators struggled to warm up the place, but a small space heater is provided; you could use this to bump up the warmth in your immediate area if you're getting really chilly.
There is free wifi, but the signal was quite weak/slow during my stay. If you don't need to do any work or don't plan on streaming TV shows/movies on your laptop, this won't be an issue, but I freelance and had issues downloading documents/loading some websites and certainly struggled to stream TV shows and watch YouTube on my laptop/phone (there is a TV from which you can watch local channels, but no Netflix or other streaming apps). The wifi signal was also often too weak to reach the bedroom full stop. Again, this probably isn't a dealbreaker unless you're in town for work or if strong wifi is important to you for some other reason.
Overall, my stay in Trinity's flat was very satisfactory and was a great home base for my stay in Manchester!
