I love google maps, it tells no lies : for those wanting to follow Gritty's footsteps, here is how you get to YWCA, with a stroller:

Yes, its the building at the top, the one with the cartier ad on it. Note the angle of the road compared to the buildings.
Along the way, you will come across the zoological gardens:

Now look down that hill you just came up:

To get to Arts center, this is what you have to cross:

Yup, that lovely bridge over the 7 (or is it 8) lane highway; yes its paved and has lots of stairs.
There is also the traffic laden walk to Central&Wanchai, but I'll leave that as an exercise for someone else.
