It takes 5-10 minutes to get to the city center by walk. You can easily reach metro station from which you can get to Ouchy within 10 minutes.
The flat was equipped with amenities described on the page and the host replied to any questions promptly.
The reason why I couldn’t give 5 stars was because the address provided by the host was different from the actual address of the flat.
Overall, I would recommend this flat for the tourists visiting Lausanne for the first time.
