Jean-Pierre's apartment is small, but recently renovated and very clean. It has everything you need to have a comfortable stay. Jean-Pierre himself is a pleasure to deal with. He's very attentive to detail, and accommodates special requests whenever he can. He showed us around the unit and told us how everything worked, and then took on a short tour of the neighborhood so we knew where the grocery store and the subway were and so he could answer any questions we had.
The location is very convenient to transit and other amenities. It is close to King's Cross station, which was historically a red-light district. That's almost entirely changed. There are still some holdover businesses, and some characters you wouldn't want to ask over for dinner, but by and large people are friendly & helpful. We never felt unsafe.
We won't hesitate to book Jean-Pierre's apartment again next time we're in Sydney.
