I have heard a lot of negative stuff about Gabs before I came here, but I have to say all of that was incorrect. Gabs is a great uni accommodation, the people here are amazingly welcoming, the JCR members and warden are helpful and nice. You will surely make a lot of friends here. You won't need a bus pass to go to the uni, all the uni buildings are no more than 15-20 mins away by walking! And literally a minute away are 3 big supermarkets, and 2 mins away is the Whitworth Park.
I have never shared a bathroom in my life, so it's a hard time getting used to the cleanliness; plus, it's difficult getting used to the dinner timings here too, but all in all, I would recommend the hall to anyone who wants to come here!
