Everything was according to the description, Andrew's sister has welcomed my friend and I and was super nice and very helpful. The place is very well located - a 30 min tube ride from St Pancras only, and a 10 min walk from Westminster and Buckingham Palace.
The bedroom in itself was completely functional, as well as the bathroom.
Perfect place to sleep in for a weekend !
Thanks again to Andrew and his sister for being so accommodating.
