The host Claire is very nice, friendly.
The location is quite good for my purpose. 6min walking from S-Bahn train station. The town Cully is a nice starting point for exploring the famous Lavaux wineyard area. Just walking a few minutes, we were inside the vineyard.
Room is spacious, clean, inside a historic old house. Bathroom is narrow but good enough.
What is interesting is: just in front of the house, there are a bakery and a winemaker, so I could easily buy some local wine.
