Anna's place is absolutely amazing! It's warm, homely, and central to all of the main sights. We barely had to use public transportation while we were there! There are also many restaurants and shops right outside, the area was very safe, and the view from her apartment is beautiful. The only thing I would note is that you will have to climb 6 flights of stairs to get to her apartment. There is no lift so it may not be good for those who are not able to climb a lot of stairs.
Other than that I would highly recommend her place! We had a fantastic time there.
