Butterfly on Wellington has a great location in Central! It's a short walking distance to the numerous public transit options (MTR, ferries, ding-dings), close to many incredible restaurants and historical attractions (check out Tai Kwun!). The rooms are clean and the bed is comfortable. There were a couple stains on the bedsheets but we were able to get new ones so that was no problem.
The regular rooms are small, so the bed is quite close to the bathroom. However, you can upgrade to a superior room with more space. The bathroom clean and modern with a walk-in shower that had great shower pressure. Rooms were quiet and we had no issues with noise. Front-guest staff speaks English and is helpful and accommodating. I would recommend staying here for the great location, good value, and clean, quiet rooms.
