Great place, in a great location.
Very clean and tidy. The 24 hour concierge was great as it meant could check in or out whenever suited.
Had an iron which was useful. Clean and powerful shower, with towels and shower gel etc provided.
Only minor problem is it's next to a fairly busy road, so can be a bit noisy... but then it's London so what do you expect! Also, the air con could be a bit noisy.
All in all, great value for money, and great hosts.
