Hubert is a great host! Very discrete, thoughtful and careful not to intervene. We chatted in my broken French and he helped me out with his English for some fun conversations.
His 2 cats are good company as well. They are curious and a bit needy which makes them a lot of fun.
I warmly recommend Hubert if you are looking to explore Lausanne by foot since everything in in the range of 15-20 minutes leisure walking.
