We have spent 5 days in this very nice house (2 adults and 2 girls aged 10 and 7).
We found it clean, comfortable and well equipped. It's in an excellent position for visiting London (bus 29 for the center and tube stations at the door step!).
The neighborhood is nice and safe. There is quite traffic in the main road which could a bit annoy who has a light sleep but nothing terrible.
Katja was really helpful in giving advices regarding mobility in the city as well as for shops. Check in and out procedures very easy :)
We fully recommend it and would certainly return!
