We enjoyed our stay in West Didsbury with 6 in the flat - the futon is very comfortable.
The transport links from here are excellent. Very easy to get into Central Manchester on the tram.
There is parking at the rear of the property but you cannot access the house from the parking spot and have to walk along an alley a few doors up to get to the front of the house. Although there is parking on the road, we never found a space near to the flat. The flat is on the first floor.
However it did the trick and we had a good stay.
