I spent three nights in a fourth floor room with balcony and lake view. The room was quite comfortable, with marvelous lake breezes from the large window on the east side and the slider door on the south. The balcony was spacious, with a table and chairs. The bed was comfortable, and there were plenty of electrical outlets, a nice side chair, minibar frig, plenty of storage and a security safe. The bathroom is small and dated, but perfectly fine and spotlessly clean.
The desk staff was always friendly and helpful, as was the dining room staff at breakfast. And with pastries, breads, fruit, boiled eggs, meats, cheese, juice, cereal, etc., it was easy to get a filling breakfast which carried me through my day.
The location is superb: five minutes from the train station and metro line. Yes, it's uphill from the station, but not very far. Besides, everything is uphill in Lausanne. The position near the train station is convenient not only for transportation, but for take-away food options for a decent and reasonably-priced meal at the end of the day.
I enjoyed this hotel, and give it a strong recommendation. I would certainly stay there again.
