We were a group of 4 students. We arrived in Manchester by bus, and Margaret kindly offered us to pick up at the Prestwich tram station, which is located about 2 miles away from the house.
The caravan located in the garden is quite large and looks pretty new. It's very well organized, and we did not miss of anything during our stay. We did not have any trouble sleeping there, the heaters were effective and the mattresses comfortable. The shower is pretty large, but the hot water time is quite short. The kitchen is well equipped, and coffee, tea and even butter were present.
We came back pretty late during the night, there is a taxi office just next to the Prestwich tram station, the ride cost £5.
Margaret drove us back to the station on Sunday morning, which, once again, was very kind of her.
To put it in a nutshell, it's a very nice place to stay, and we did not really expect that level of comfort in a caravan. I recommend this place if you are coming to Manchester for a few days!
