Chain wins for: brand consistency, central locations, single travellers
A SACO in central London delivers a predictable experience. Same fit-out, same standard, same loyalty programme. If you book the same room 12 times a year on business and need the consistency, chains earn their premium.
TNS wins for: crews, vehicles, value, regional cities
Most serviced apartment chains are studio or 1-bed in city centres. Crews of 4+ end up in 4 separate apartments. TNS whole-house is one address, one invoice, one set of keys. In secondary cities (Coventry, Stoke, Wolverhampton) chains barely exist; TNS has partner properties there.
Honest pricing comparison
A 1-bed Citadines is £140-£200/night in most UK cities. A TNS 4-bed house is £150-£200/night. For solo travel, similar. For crews, TNS is wildly cheaper per head.
