This. Extremely important, also if you are just renting. Do you have any tips to evaluate this? When visiting an apartment it is hard to know if the neighbor’s TV can be heard while you’re trying to sleep… I have moved recently to a rented apartment and noise from neighbors is something I hadn’t heard while visiting but that is rendering my life quite miserable in here. I even wonder if it can be considered a defect that was not visible during the visit therefore entitling me to a rent reduction!
BTW, do you offer your services in Suisse Romande?
