We stayed at the appartement for four days, and the house is what it looks like on the pictures. There is enough space for four people and a relatively big kitchen (which we did not use). The location is good, with some nice pubs nearby and a 10 minute walk to the underground (blue line). It is just a few stops till the city centre, which was lovely.
We slept fine, the mattresses were a bit soft, but that is just preference. The only downside was that it was not as clean as we thought. The rugs in the bathroom and bedroom were not really clean (hairs and stuff). So that made us a bit uncomfortable. Still, it was a nice place to visit London and see all the great things the city has to offer!
