There are to be 2 years of major construction work in the streets nest to the Windsor and these go on all night - because that is when the metro is closed! So the general city centre street noise and calls to prayer pre dawn are drowned out by tunnel borers etcetera.
Add to this the scary state the wiring, the grubbiness of the curtains and rugs, loose carpets on the stairs and antiquated plumbing and frankly, following the footsteps of some famous people may be better achieved elsewhere.
Pity because the staff try hard in an old fashioned way, they just cannot fix a problem this big without a major investment: in their place I would use the two years of mayhem to renovate the place but maintain an early 19th century feel by decorative style, if I could rise the money.
