If you want a quite and peacefull sleep, don't go! The airco is on 24/7 and makes too much noise. I had 3 (out of 7) bad nights. After the first night, the host said I could turn it off if I couldn't sleep. So I did later in the week, but half hour later she turned it on again!
It's an old house, so the noises travel far and everywhere.
The neigbourhood is quite and safe. Not far from bars, restaurants and busstops (to city and airport). Fast internet, smooth check-in/out.
