We stayed at Milly’s place for 3 nights, and it was quite a comfortable stay. We are a family of 3 with a kid. There was enough space for us to rest and sleep as there were 2 sofa beds in addition to the main bed. Ours was flat A, it was on the ground floor just next to the main street so understandably it was a bit noisy- not a big issue for us. The flat is just at the city centre and it was so easy to get around Manchester from there!
The kitchen and toilet had all necessary amenities.
Overall, I would recommend this place if you were going for a trip with a little crowd and didn’t mind being on a busy street - the stay is very comfortable with a cooperative host!
