This was our second stay at Base. We stayed 4 nights. We stay here when we go to Sydney because the location is fantastic and we save a few dollars by staying at a backpackers as opposed to $400+ a night in a hotel in the same location.
We stay in the double room with an en suite. The room and en suite is always clean. There is some obvious wear and tear (scuffs on the walls/crack in the toilet seat) but for the price we felt comfortable. Yes there is a night club that plays music loud every night but we're heavy sleepers so we don't mind. I thought it was cute that there was ear plugs provided on the pillows.
Town Hall station is literally across the road and Cockle Bay & Darling Harbour is a block away. You couldn't find a better location.
The only cons were that they only provide 3 pillows for a King size bed, you need to ask for a remote if you wish to use the TV in the room and our air conditioner turned itself on and off every couple of minutes.
If you choose to spend most of your time travelling around Sydney and need somewhere to crash it's perfect. I wouldn't recommend to light sleepers or travellers who like to spend a fair bit of time in their room.More
