First the pros - if you love shopping and want to be literally right next door to the department stores, this could be your ideal apartment. Access was very easy and the hosts communicated quickly.
The cons - it was so noisy throughout both the day, and importantly, the entire night we decided to move out early. We stayed a Monday & Tuesday in mid-January. At night we heard a homeless man - angry about being moved, then party revellers; followed by (from 2 or 3am) delivery trucks servicing the department stores. Despite the double glazing and window shutters, we didn't sleep at all, as it was very noisy.
The other downside was the small bedrooms and short beds. The photos in the listing were of the bigger apartment next door. Our bedrooms were all small, and not helped by the fixed closets which mean you can't leave an open suitcase in the room. We're a relatively tall family (all around 6ft) and the beds were very short, especially the twin room.
I'd avoid staying downtown again.
