We really liked staying at Michael's apartment!
The location is incredible, right in the heart of the city and close to everything you might possibly need. We actually spend nothing on public transports (only the trip from the airport), since you can walk to everywhere and city center is not that big.
The space is small, but that's also part of the charm. It was our own cozy and warm place, where it always felt so good to arrive after walking the around the city. We really needed nothing more than the comfy bed, tv, kitchenette and bathroom... it was great.
Michael was easy to reach out, and check-in was simple. Whenever we return to Manchester we would gladly stay here again.
