not positive what's meant by room 'maintenance'.....? the entire hotel is old, historic even. so i'd call the rooms 'old' in style. but certainly kept up to date in terms of cleanliness, thermostat, fixtures, etc etc. as on old hotel, the rooms - across class, and i've stayed in several - are grand in scale. soaring ceilings, classical finishes, tons of open space.... showers aren't going to have 12 heads and there's no toto toilets. but i've always found the water pressure more than good enough. it's all in the beholder's eye: some would call the locarno 'dated', and it's a fair assessment, but these same people might just as fairly use the same term for the king david, or claridge's, or the beverly hills hotel.

i wouldn't say it's the kind of hotel one chooses for brand new state-of-the-art facilities, plumbing, etc.
having stayed at two brand new hotels in the past month (conrad in DTLA and canopy in minneapolis), there's definitely something to love about that kind of experience. but that's not this hotel. that being said, newer hotels spend untold sums trying to achieve what comes to hotel locarno naturally. class, history, patina, confidence. if sparkling new is what you're after, you may be better off at this new six senses, or edition, W, etc.
