This is a well proportioned house in an excellent location. It really is only 2 to 3 minutes walk from Kew station and a good array of small shops, cafés and restaurants. You can walk to Kew gardens in 15 minutes. We were always able to park the car on the street within 10 yards of the front gate - a rarity in this part of London!
The house contains everything that a family could reasonably need. Apart from an hour on the Saturday morning when it was down, the WiFi worked brilliantly. The house was clean, although, as a previous commentator observed, a little tired. I believe that Alexa has plans for renovation shortly.
Things to be wary of: as in all this area of West London you might need earplugs if you want to sleep much beyond 6.00 am, due to the noise of aircraft coming into Heathrow airport; make sure that you close the bedroom doors tightly - Tinka is a very nice cat, but would regularly find her way onto a bed, bloodying a sheet with a dead mouse on one occasion.
One of the most positive aspects of staying here is the very responsive nature of Alexa. When we did have minor glitches, regarding bed linen and parking passes she was extremely quick to respond and deal with them. I would certainly recommend this as a good place to stay.
