I asked for a quiet room but was given an incredibly noisy one. Only single-glazed, it faced directly on to all-night-busy Princes Street - along which ran trams, buses, trains, & ambulances with sirens etc. I got no sleep at all.
Also, my bathroom floor flooded from below every time I turned the basin tap on. My nightmare room was no.1.8. Maybe other rooms were less horrible? I won’t be using this hotel again.
