The hosts are really nice and react very quickly to questions and requests. Also, they even put your name on your mailbox, which was for me quite surprising and nice!
The apartment I had for 2 months was facing the street and it was quite loud when trying to sleep at night with an open window. With the window closed, you can't hear much of the street. The walls are quite thin, so if your neighbours are talking and not trying to be quiet, you will hear them, often quite clearly.
The apartment was very clean and everything you need is provided, e.g. dishes, cutlery, equipment for cooking, an iron, a drying rack (on top of the wardrobe).
So to summarize, if you are sensitive to noise (while sleeping in summer or during the day) make sure to double-check with the hosts to get a quieter room.
