I just found a better place for stairs climbing! It's Blk 28B/28A at Dover, near Dover MRT station. Just walk away from Singapore Polytechnic and u will see 3 tall blue HDB flats. Walk in to the vicinity, and u will see a cluster of super tall buildings, some are still under construction, while others completed. Just walk into that vicinity and u will see the signboard which depicts 28B/28A. Just climb it! The staircases are just behind and beside the lifts, in the lift lobby. Open the door and enjoy the postcard scenery at level 40! It has 760 steps, if my calculation is right.That means, just climb 1 full 40 storey, and then 29 more, and that will be a little more than 1336 steps! That's Swissotel's vertical marathon!
