This location is ridiculously good - steps away from embankment station, pret right down stairs, short walk to covent garden.
The two bedrooms are small, but perfectly serviceable. I was worried it would be loud at night, but it really wasn't bad at all - we heard a bit of noise from the street but nothing disruptive.
There are 3 pretty steep flights of stairs, so keep that in mind!
I'd definitely stay here again.
