Hi Marzo
Dont know the exact location of no 6 - but all I can say is that there are a lot of steps from the top down to the road - over 200!!!
Wouldnt be too bad going down - but wouldnt like to tackle them going up - especially during the day when it is really hot.
At night once you have come down the steps you are only 5 mins stroll to the Irish Quarter.
If you end up in the Square you would be about 10 mins walk back to your apartment - still a bit of an uphill trek I'm afraid.
Some of the roads around that area do look very steep and can be a bit dangerous as they are those slippy tiles.
I'm sure you will be fine, we spoke to some people who were staying there and they didnt find it a problem
