We loved staying in Ana's flat!! It felt completely private, but at the same time there always seemed to be someone around when we needed it. Ana and her family were really caring and welcoming (we were brought extra water and snacks occasionally), and when we asked about a can opener they replied and brought us one within a few minutes!
The flat itself was really clean and functional. It doesn't seem to get a ton of daylight, but that was OK for us since we were out most of the day. There is also a little table outside in the garden which we used when we did eat in the home :)
In terms of the location, the house was a 10-15 minute walk from a metro station and there was a shop selling groceries really nearby. We felt safe in the area.
