5 stars for the location. It's located in central area with convenient access to Hong Kong station. Walking distance to supermarket, food and shopping. On the flip side, it's close to bars so might be little bit noisy in the evening.
5 stars to the host who was nice and responsive.
3 stars to amenities overall because bathroom was tiny but that was expected. I don't think I could a better place with this budget.
Tip: ask for hair dryer and towels beforehand
