We had a nice stay. Previous reviews were very accurate - the walls are very thin, and yes you regularly hear neighbors in adjacent dwellings.
The hosts have an automated noise alert system in their units that apparently, automatically, report via email to every one of their visitors that someone has triggered the system. So, we woke to an email that came in at 3am explaining that we had been too loud - but we had headed to bed at midnight. I responded to the email looking for some clarity considering it couldn't have possibly been us - I was told "it probably wasn't you". This system could use some improvement!
It doesn't feel good to know you've been behaving as requested and get an email anyhow that says you were not.
