Martha's apartment is really nice and well located - 15 minutes walk uphill from the train station. We were very comfortable in her apartment (2 adults snd 1 child) and had everything we needed. It was a public holiday and most shops and restaurantes were closed, which made our arrival tricky and unfortunately Martha wasn't there to meet us, she left the keys in the mail box. It would have been nice to meet her and get some local tips but it happens! I would recommend to stay at her place in Lausanne!
