Ho soggiornato una sola notte e la camera che mi è stata assegnata è risultata essere delle dimensioni. Colazione, al buffet, ricca e curata. Il servizio di navetta che ti conduce e riporta gratuitamente a Mandela Square…

Does The Catalyst Apartment Hotel by NEWMARK have wheelchair accessible rooms?

The property lists step-free or accessible facilities.

The property lists a front desk staffed 24 hours, so a late arrival should be possible. Standard check-in is from 2:00 PM. Rooms are still released after a cut-off at some properties regardless of the desk hours, so tell us your arrival time and we'll have them hold it.
