We stayed at Mandip's property for one night prior to a flight from Heathrow.
The unit is simple but was ideal for our purposes. It was clean and the bed was comfortable, the shower was wonderful, hot and strong. The most important things. We took a taxi to the airport, cost was 30 pounds direct to the terminal, but you could take the Elizabeth line from Hayes and Harlington if you wished to avoid the cost.
The heating didn't work from the controller in the unit but a lady at the house in front started it for us and it worked fine then. Breakfast consisted of cornflakes and milk with bananas and choc chip cookies, tea and instant coffee was available in the unit.
A couple of small annoyances. The key was to be collected from a keysafe but although we worked through the Airbnb listing we couldn't find a code for it. We eventually knocked on the front door of the house and a lady told us the code. And we planned to walk from the Hayes and Harlington station to the accommodation as Mandip estimated a 6-7 minute walk. Maps walking said 17 minutes and it took us over 20 so it's quite a walk, a taxi would be better unless you like walking.
Overall though the unit suited us fine for our purposes and was cheaper than most which is why we picked it.
