1) Good location, just be careful when trying to find the apartment. It's on number 39 but then you continue and turn left into a smaller street.
2) Not suitable if you need access to your phone, there is no signal because it's a basement but you can go up a few steps and make a call just fine.
3) I never saw the washing machine. I was told when I was about to leave that there is one in the building but I can't confirm it.
