Our stay at Jack's place was extremely short, but nonetheless, we were extremely comfortable throughout. Jack was around for check-in even though it was almost 9pm. You have access to pretty much everything you can find in the communal area which is spacious and clean. We were staying in the bedroom on the ground floor which although is small, does the job - you have your own private area with access to the patio (due to the continuous rain we didn't get to use this). The bed itself is pretty big and comfortable. Our bathroom was super clean and the shower is great (good pressure and spacious)! Jack puts a lot of thought into his home and has pretty much anything you need from slippers to toothbrushes oh and for any coffee lovers out there - there's a good ol' Moka (huge one) :) He is also on hand if you need anything either in person or via Whatsapp.
In terms of location, we were going to the athletics stadium by the Etihad which is a 5 min drive away. We didn't venture into the city centre but Jack told us it isn't far. There is an Aldi supermarket at the end of the road too.
Overall, we would fully recommend staying at Jack's place and we will most certainly be back next time we are in Manchester!
