I stay at the Quest Apartments Castle Hill for business trips on a regular basis. It is conveniently minutes away from my business destination and easy to get to with the use of a hire car from the airport. The Quest offers secure, under cover parking for free.

I generally stay in the Studio rooms or 1 Bedroom Apartments for between 2 to 5 nights at a time. Both have fully functional kitchenettes which are a great budget option for those longer stays. If want a good cooked breakfast at reasonable price, cafe Gionta is right next door and open fairly early. You'll get yourself bacon & eggs & a good coffee for around $13 to $15.

I am always greeted at reception with a cheerful smile and efficient processing. I regularly arrive late (traveling from Perth) but reception is open until around 11pm.

I have always found my rooms to be very clean, tidy, comfortable and functional. The cleaning staff do a great job. I can count on my room looking the same as when I arrived every night when I get in.

Alternate accommodations in the immediate area are the Hills Lodge and the Crown. Both are also good stays but you can expect to pay more per night and will also pay $20-$25 for a similar cooked breakfast. The rooms in the lodge I feel are looking quite tired in some of the Queen rooms.

Overall, I feel the Quest is great value stacked up against it's local competition and recommend it to work colleages. I will continue to be a returned guest.

We were looking for a motel room in Sydney's north west and, guided by Tripadvisor reviews, booked for a one night in a Studio Apartment at Quest Castle Hill. What a find!We stayed an extra night, rather than take a chance on what we had previously planned. It's modern, clean, spacious, quiet, comfortable bed, has opening windows!!!, has a fully-equipped kitchen (for 2 people, in a studio apartment - so don't plan a dinner party for 6 there!), friendly and helpful staff, undercover security parking, good shower, reasonably priced, and (if shopping appeals) a wide range of outlets within walking distance or a short drive to Castle Towers. So highly recommended. We'll be back, whenever possible staying there on necessary regular trips to Sydney.

(Note: if you're a tourist to Sydney, Castle Hill is a long way from Sydney's CBD and, whilst this is great accommodation, is not really for you.)

Tip - Book via questapartments.com as you'll find the cheapest rates there.

Stayed 10 nights in this place. The apartment and service cannot be faulted. The apartment was clean and well appointed. The only gripe is that they could have put in a TV in the bedroom. The facilities like the gym is also OK, and the shuttle service to nearby locations is a good idea. Service is good as well, friendly, informative.
However the location itself is not good. As other reviewers have said it is tucked away from the road alongside panel beaters and catering companies. Food options are as follows if you do not have a car.
1. cook yourself
2. delivery (the two options provided by local restaurants have a minimum delivery fee and seems pricey for standard takeaway cuisine)
3. walk to pub - 10 minutes, lakeside restaurants - 20 minutes
4. grab a cab to nearby restaurants

I find this accomodation average and slightly over-priced. I had booked a studio room for 2 nights over the weekend. Being a weekend, it was not serviced...
The queen size bed was kinda small, bathroom was kinda small and room quite cramp...I guess thats just how a studio room works around here.
Aircon seemed to be quite stuffy and how these studio rooms work is - you have to open a main room door that splits to 2 different rooms (Eg. 401:- 401a and 401b)....therefore it can be quite noisy. Next to us was a family with 2 kids and in the morning we can hear them banging the doors, running and shouting.
The bathroom was also very small and I feel like I have overpaid for this room. I had paid AUD120 a few nights ago to stay at Novotel Rooty Hills and that room was like 2 to 3 times bigger!

The bed here was small but comfortable sheets....only thing the pillows were nasty. They were really flat and not of any good at all.

Studio rooms do not have any washing machine but you can use the ones below next to the reception for free. Free parking too....broadband internet access is payable, no wifi which means you can't connect via iphone/ipad....this needs to be upgraded. It's the apple revolution now guys!

Overall....6/10
I wished I booked 1 night instead of 2 but I have already prepaid
could do better ...

location wise: dont even bother if you do not drive
