We had a negative experience staying at Louis's place. Mainly because it was not at all as clean we expected after reading previous reviews. Floors were dirty, there were dirty socks under the bed as well as lots of dust... There was also mold in the washing machine, so we couldn't use it.
The sheets although seemed to have been washed were old, dirty and ripped.
The windows were all dirty as well covered in oily fingerprints.
Also, which is not the host's fault. The apartment is facing a really busy street which means it can get very noisy.
