Sophie gave me a very friendly and warm welcome. She explained everything I needed. It's really nice to have your own front door so you can come and go as you please.
Unfortunately I didn't sleep very well during my stay in this flat: it's on a very busy road and the weather was 30+ degrees. If I opened the window, it seemed to amplify the sounds from the cars. And there are cars 24/7, even at 4 in the morning. To get an idea for how loud it was: I was watching a movie on my laptop and even at full volume it was often drowned out by the noise of passing cars. Fortunately the closed window is pretty good at insulating against the noise.
I would recommend this flat only if you expect the temperature to be at most 25 degrees C so you can keep the window closed, or if you like a really warm flat, or if you are sure you don't mind the noise.
