Nikki's place is AWESOME -- it was absolutely a second home to us while we were travelling and exploring Sydney. It was so comfortable and welcoming that we looked forward to going back 'home' at the end of every day! The location is also perfect due to its proximity to the train station -- literally a couple mins' walk.
Nikki is also an incredible host -- 100% committed to making her guests feel welcome. When we met with a couple of hiccups (eg: household stuff that had run out), Nikki was so quick to find a replacement / resolution so that we weren't in any way inconvenienced. She's definitely a superhost!
Would absolutely stay at Nikki's again if ever we were to return to Sydney, and would 100% recommend her place to anyone visiting!
