We are just home from a 5 night stay in this apartment with our 13 year old son and we have nothing but positive things to say about it. We absolutely loved it.
The check in process was straightforward with clear instructions in advance. The apartment is exactly as described and the location is unreal, a 2 minute walk from Oxford Street underground. There are cafes, bars, restaurant's and shops on the doorstep. So much of London's west end is within walking distance.
It is spotlessly clean, has excellent wifi and the kitchen has everything you would need.
We will definitely be back.
