Loved our stay! (We upgraded to a bigger unit due to having two families stay in the unit, but pretty sure the review still applies to original posting):

Coming from America for week, we were first impressed how immaculate the flat was. So clean, just as pictured.

Brand new development, washrooms were roomy and luxurious especially when compared to other European homes we visited.
Locals who visited us were surprised we were in West Drayton.

Main living room had enough seating for 8+ comfortably.

Pros:

TV with Sky programming – lots of channels and movies. Including International.

Having a grocery shop downstairs (Stainbury’s) was a huge plus! Made several visits. There’s also a fish and chips shop.

Sometimes it’s the little things that make you feel welcome, we were greeted with treats (welcome basket), and since we had a little one, there was some milk for us in the fridge. Awesome!!

Plus, we were contacted several times during our stay to make sure everything was good.

5 minutes from Heathrow.

Cons:
We opted not to have manuals, and had tough time with the AC/heating. Also the washer /dryer all in one didn’t work to dry clothes. Had to hang and air dry. The dryer doesn’t work well. For a seven day stay, more provided linens and towels would have been nice.

Overall, it was a great experience and we would definitely stay again on future visits.
