I would emphasize reading reviews before booking. I read reviews for the lower unit about noises upstairs and reserved the upper unit to avoid this. As an older house owner I understand noises and simple inconveniences but there is quite simply no insulation or way to keep another unit quiet. Mere talking from another area can be heard clearly at any time of day- which potentially can get you fined and removed from your booking. We just needed a place to sleep and it served this purpose, but I think it’s important to level set expectations
