Karen's place is in a great location and has everything you need for a trip to Sydney. She is super responsive, accommodating, and outgoing and friendly. She really worked with me on checking in early as I was really tired when I landed. The only things to consider are that if you arrive before the check in time, you should avoid the hotel staff in the lobby, which can be interesting. Also, if you're sensitive to noise and a very light sleeper like me, the apartment is on a busy street that gets loud during the weekdays from 6:00-22:00, so I used ear plugs. Otherwise, everything was a great and it's highly recommended.
