Roezetta's place is lovely- location is awesome given how close it is to Central station and it's a very cute layout and good use of space. It's quirky like most renovated old Surry Hills places but if you're planning on being out and about most of the time, it's a great place to just crash out. Bed is comfy, bathroom clean and water pressure is good. Great little kitchen and seated area outside for chilling out! It can get quite noisy/ echo-y given it's hard floors everywhere from the neighbouring apartments and it's hard to block all the light out for sleep so if you're a sensitive sleeper you need to take that into consideration.
The check- in process is pretty easy; do advise you do reach out to Roezetta and clarify things as she's very friendly and attentive and where possible will help out with checkin times etc.
Also it's great to have a car park but if you're going to use it, really need a small car; it's a very tight squeeze and you HAVE to go in front first.
