We had a great visit at Tom's when we stayed the first week of November 2018. It is about a 10 minute walk down Argyle St to the Sydney Harbour Bridge and the Opera House. It is a great location.
If you are looking for an inexpensive alternative to the Bridge Climb, check out the Pylon Lookout, which is a short walk from Tom’s place. You are able to see all of the same views you can from the Bridge, and it's only $15.
The Rocks is a very authentic neighborhood not far from the Bridge. Pancakes on the Rocks is very delicious and 24/7. Barangaroo Reserve is a short distance with a lovely walk around the water.
In the other direction, about a 15 minute walk, is Darling Harbour with lots of restaurants, shopping and fireworks Saturday nights at 9 pm (tip: we had a late dinner outside at the Hard Rock Café which gives you a fantastic view of the fireworks over the water). If you are looking for an excellent harbour cruise we highly recommend Sydney Harbour Boat Tours.
The apartment is very spacious. There was a bottle of champagne in the fridge upon arrival. Bed is very comfortable, toiletries in the bathroom, washer/dryer very helpful, and a view of the water from the balcony. Highly recommend!
