The room was clean but also pretty spacious for a flat situated in London.
The cooking facilities were very useful.
The toilets and the bathroom were immaculate.

Nathan was a pleasant host.
He was friendly and never disturbed me with anything.

The only negative point is that the façade of the building was being renovated as I was there, and the workmen started every morning at around 8:30 which meant you had to get up "early" or to sleep with earplugs.
Be carefull, this comment is of August 18th of 2014. What I wrote about the noise due to the façade renovation is maybe a thing of the past.

Anyway, I strongly recommend it.
A great experience :)
