Worth the price.
Clean, comfortable, quite spacious. Yard (large, grassy, trampoline, basketball hoop) must be a hit with kids in summer. There are AC units in the suite, although we do not know re. their efficiency (we are assuming it's good :)). Internet works well.
We found the area great - as many have said, super close to train station, small shops, a great little Indian restaurant (Indian Villa).
Phil's gracious offer to store the luggage after check-out is another great asset.
A few things that some guests may want to consider: the train station (Ealing Common) does not have an elevator and there are 2 flights of stairs (quite a number of train stations in London do not have elevators); the kitchen is not too well equipped for eating or for cooking (but there are many nearby places to eat out); you can hear the trains, especially at night (but not an issue if you keep the windows closed).
Ultimately: we do recommend Phil's place.
