The flat is located in the outskirts of Lausanne, but it is quite fast and easy to get into the city centre by public transport. It is nice and clean, and has pretty much all the amenities one needs. Epalinges, the town where the flat is located, is nice and quite, being also close to nature.
If you come by car, getting the parking spot is a good option, as the alternative of street parking is not great. When we came there, the building's parking area was closed after 2 days, so for the rest of the trip we had to deal with street parking, which is not fun if you want to leave the car behind, and use public transportation or cycle to other places. Samantha was kind enough to ask one of the neighbours to let us park on their spot every now and then.
We had a small issue with the heating, as the flat was quite cold in the morning, but we got lucky as the weather got very warm a few days after we got there, but hopefully it was just a temporary issue.
