Pros:
1. Very cheap for a room with a private bathroom, and even much cheaper for dormitory.
2. Quiet and warm
3. Free luggage deposit on the day of arrival and check-out.
4. Near central station and Haymarket. Convenient traffic, easy access to cheap restaurants and supermarket.
5. Free to use kitchen that you can prepare your own meals
6. Helpful staff
Cons:
1. Room is a bit dusty (not bathroom).
2. You must prepare all daily necessities yourself, the hotel is more a dormitory than a hotel (acceptable for such low price).
3. Staff is off duty from 22:00 to 9:00 next day, so you're on your own in case you need assistance.
