Idk whether to rule it out or just get it because it’s nice and it fits all other criteria and it’s been hard finding the exact one
If you're within ten minutes' walk of one station and fifteen from a further two and everything else is perfect, I'd likely give it a go provided the price was reasonable. It does also depend on how you work to some degree - if you mainly take bookings in advance rather than at short notice (less than an hour or two, say) then I think it's less important too. It also depends which part of town you're in - Chelsea has shit transport connections, but I always assumed it's because the locals either swan around in their 4x4s or take cabs everywhere

I'm two minutes' or so from my nearest station and have another three or four within five (plus four mainline stations and God knows how many underground stations within ten minutes) but that was pure dumb luck and I pay well for it. If the nearest station is nine minutes and it's an easy, straightforward walk (and preferably serves at least two different lines) I'd think it would be OK. If the weather is that bad they can get cabs
