In short: We had a wonderful experience. In more detail: Communication with Sara before and during our stay was great. The house is in a vibrant area, but still it is quiet in the house in the evening and night. The metro is in 5 minutes walking distance and you can get to most of the tourist hotspots quickly. The house itself is a gem imho. Look at the pictures and you will see what I mean. You really get what you see, it's great! I can highly recommend staying at Sara's house!
