The pros: The room was nice, the facilities (the guest bathroom next door, and the seperate guest toilet down the hall) were fine, and you have access to the kitchen if needed. The place seems clean, light, airy, spacious, and overall presentation of the apartment was good. The host seems friendly and welcoming on entry, and she shows you around the home when you first arrive. Location wise, it is close to Lusanne and for my purposes of visiting the local area by car, it was convenient. And last but not least, the cost is affordable, particularly for Switzerland.
The cons: You are living with a family and a young child (who seem nice but..), and I don't know if it is the design or layout of the apartment but noises seem to be amplified. For instance I was told I was closing the doors too loudly (and I assure you I was closing the doors normally! ) There is also a no noise rule between 10pm-7am which seems pretty strictly enforced. This includes taking showers which I think is not convenient for travellers who are out all day. For example, I did come home pretty late, but I was out all day and had just hiked a mountain and I was starting to take a shower when the host started banging on the bathroom door shouting through the door I couldn't take a shower at that time. I feel like such rules are very restrictive, and you need to be able to use the facilities freely whenever you want, not worried about bothering other people when doing so. However, this is a room and you are living with other people, so it is what it is. Lastly, perhaps a few communciation issues when you only speak English, but the host does her best.
