Uh, starting from where? It's walking distance from the Puduraya bus terminal, Pasar Seni LRT, and Majarajalela Monorail. There's some confusion in the placemarks if one does a search on Google Maps. The lobby is on Jl Sultan, south of Jl Hang Lekir. The layout of Jl Sultan is somewhat confusing in this area. It goes from North/South to West/East in this area and keeps the same name.

Try firing up Google Maps and doing a search on, let's see, Swiss Inn, Kuala Lumpur, MY.
