I rented an apartment in Reykjavik, Iceland for 3 nights. The host had nothing but positive reviews and advertising a "quiet residential neighborhood". From the moment we unlocked the door, there was construction noise from a nearby street (jackhammering) all day. When that finally stopped, the upstairs neighbors started banging all night as if they had their own construction site going on upstairs. I tried to let it go the first night and didn't say anything. Then it happened again the second night until 3am. Then again the 3rd night when I finally said something at midnight. The host didn't take any responsibility and Airbnb asked me for "documentation". Then I wrote a negative review about the noise and they never posted it. It's rigged to make them money and avoid negative reviews. Beware! I'll never use Airbnb again.
