I stayed at Anna's place for a month in May. First and foremost, it is a great location where you can walk to anywhere within 15 minutes and are surrounded by lots of amazing cafes and restaurants. But it is also very quiet. Because it is on the first floor, you hear people coming and going sometimes, but it is not at the level I was bothered by. This place is airy, big, open, and clean. There are plenty of bedsheets and towels. The only downside for me was not having a washer since I stayed a month there. I had to use a laundry service right around the corner which charges by the weight. But overall, I strongly recommend Anna's flat to anyone traveling to Prague.
