The property is lovely and was perfect for our stay in all areas except one. It has significant issues with sound proofing.
From both the basement bedroom and the first floor bedroom we could hear almost every noise from the intersecting flat. We had the joy of being able to hear the neighbours using their bathroom, having sex, playing music, walking around (sounded like they were moving furniture) and were even privy to conversations where the tenants complained about "being told to keep quiet in their own home". At least we knew that Stephano had tried to get them to keep the noise down. Presumably they could hear everything from us too.
We were a group of friends there to have a good catch up and go out for drinks, so it wasn't like we were in on the evenings and expecting to go to sleep at 10pm. However on the first night most of the group had been up since 4am and wanted to sleep at midnight. The neighbours had other plans! :(
