We had a decent stay overall. The flat is really well located in a quiet neighborhood with good access to all manner of things. It is relatively spacious and has nice kitchen facilities. The only issues we had with the space itself were that the ceiling in the loft is very low (so sleeping up there is difficult), and lighting is very dim, especially in the kitchen area (making cooking and cleaning at night difficult). Otherwise, very nice!
Elsa provided a lot of information about getting around and was quick to answer messages. However, several weeks before arriving, as we were messaging (politely) about a point of confusion in the listing and she suddenly became nasty and passive aggressive. I felt very unwelcome in the flat as a result—not because of the confusion or the disagreement but because of the sudden accusatory messages.
Relatedly, make sure that you read all portions of the listing very carefully before booking, as there are a number of contradictions throughout.
