First, I should say that I am probably not the typical renter --- I actually lived in Morges for 3 years and (more or less) knew all of the ins and outs of living in Switzerland (and Morges). So a lot of the things that a host would normally help with I didn't need (so can't really comment on them).
What I can comment on is the flat itself, which is in an amazing location, and the price, which was equally good. The apartment is right in the middle of the town, which puts you steps away from all of the stores and the bi-weekly market. Occasionally you can open the window and be serenaded by a street musician. The train station and park are easy 10 minute walks, the lake and bus are 5 minutes. The apartment has everything you need (I forgot my umbrella, but they had one there I could use). And the price is comparable to what you would pay in rent (on a yearly lease) so I can't see finding a better deal for what is offered.
