What a great apartment! Great space for friends traveling together - we had one couple and two singles and the space was just perfect. The bedrooms are quite large and comfortable, with lots of storage, and the apartment is beautifully filled with light just as advertised. Really clean and well-equipped; we appreciated the washer and dryer.
Fantastic location on the "Lac" side of the train station (just a couple of blocks walk from both the train and the metro) in a quiet residential neighborhood with markets and cafes. You can walk down to the promenade on the lake or up to the old city... or easily take the Metro, whichever is your preference. And the ease to the train station for day tripping is really a plus. We were in Lausanne for 10 days, so had a chance to get a good sense of the city - and for location and comfort I will absolutely choose this apartment when I come back!
