The appartment it's really cute and provided with everything you may need to live there:
kitchen it's well furnished
Wi-Fi perfect
Bed and sofà both comfortable.
The street where the appartment is located it's calm both during day and night.
Train station it's a 10 minutes walking, and from other 10 minutes to reach the vieu ville.
10 minutes even for the lake.
A supermarket it's a 1 minute walking, and the same for a beautiful big park.
Check-in without meeting the locator..but easy. Anyway the owner answer fastly in case of contact.
My first option for Lausanne if I will be back there.
