My husband and two school age children stayed in David's home for six nights and had a great stay.
The location of the house is excellent. We found Erskineville/Newtown to be a very lively neighbourhood with lots of great cafes and restaurants - we loved Bourke Street Bakery for morning coffee and pastries, and Maggie's Thai was so good we picked up take away for dinner twice! The local grocery store is also an easy walk from the house. The train station is only a 5 minute walk away and we found Sydney's transport system to extremely easy and reliable.
Check-in was easy and we found the house in good order. Free wifi and Netflix were very much appreciated - especially by our children! Having some basic groceries and toiletries on hand for our arrival was also nice. The kitchen was well-stocked, although many drawers were quite tightly jammed, but most items could be found after a little searching.
The benefit of having a train station so close by does mean some traffic noise as the trains go by - the front room was the noisiest, so just a word of note if you have light sleepers. Our boys slept in the front room and after long, busy days they did not seem bothered by it! Also, as another reviewer noted, there is very little space to unpack/hang as I gather the house is in full use when not rented, but there were a few drawers and hangers available that sufficed.
Overall we had a great stay at David's.
