Pros: very very very quiet. Elevator. Well stocked kitchen and large fridge. Extremely responsive host. Fast wifi. Lots of restaurants, grocery stores, and transportation. AC (although it never could cool below 25C).
The only major negative was the mattress, which was extremely hard and uncomfortable. I tried laying on top of 2 folded duvets and my back was killing me. I ended up buying a $8 pool blow up raft and added that to the top of the bed to stop waking up every few hours from back pain
