I haven't stayed there for a couple of years but prior to that I was a regular. Nothing but praise from me for the Landmark...it is an old style hotel, but is well maintained.
Being older, perhaps the walls are thicker. Never had any noise other than passing Indians outside in the corridor, but being more expensive, they are not common. When I stayed there - no joiner fee, but the security took the girls card and called in the morning when she left to see that all was OK before she left.
I as at the downstairs bar (Huntsman) last Saturday and had a ripping night with dancing and live music.
