I was in town for a few days and needed a place to stay before I travelled to London.
the hosts were good people who were readily available - office trailer is right outside the apt building. The place itself was clean and it had adapters for US electronics. I would say it is the perfect size for one person, but anymore it could get cramped. The one con about the place would be the outside traffic noise. Not a big deal as I didn't fly all the way to Manchester to sleep.
I think one of the biggest positives to this place to anyone who is travelling around UK is the location. It is a 5-10 minute walk to Piccadilly Station. This station goes to and from the airport as well as directly to London.
