The bad reviews for this place are unwarranted. It's super central and super cheap. The room was clean, the bedding was clean, and the shared bathrooms were cleaned everyday. There was always soap in the dispenser, paper towels in the holder and toilet paper in the cubicals. Not sure what people are expecting for a place that's a quarter the price of a hotel.
The room doesn't have a window which is great for sleeping late and every room is ventilated with fresh air. The rooms have pretty good sound insulation and compared to a hostel it's very quiet but not as quite as an up market hotel.
The City Stop mini-market out front is almost always open offering ok food personal items and even luggage storage.
If you want a place to sleep and save on Uber rides while you explore Wellington this is a great location. If you want to hang out in your room all day, stay somewhere else.
