I stayed in Olivier's apartment for four nights. I did not meet him as he was traveling but he arranged for a neighbour to pass over the keys which worked without problems. Very good and clear communication before arrival, which left no questions unanswered. The apartment is perfectly located opposite King's Cross Station. Lots and lots of transport links make it the perfect spot for exploring London for a couple of days. The apartment is very clean and cosy. There are lots of European plugs available which I found very convenient. I had a great experience staying with Olivier.
