St Marks Randwick provided good value as it was clean, safe, and comfortable. The hotel is about 5-10 minutes walk to local buses and 15 minutes walk to the tram station; about 40 minutes to Circular Quay.
The room and amenities are basic, but they had everything I needed. Good for a short stay in Sydney, especially if you will be out and about.
2 disappointments though - 1) the ac does not work well. I could not feel any air even with fan on highest speed and temp at lowest setting. I had to leave my windows open throughout the night. Sydney is humid so sheets and hanging clothes get musty. 2) the wifi is frustratingly slow during the day. I had no problems with the wifi late at night and early in the morning, but at 8 am and through the day, the wifi is so slow that I could not do any remote work.
Overall, good value and good stay for an affordable holiday in Sydney.
