We had a great time in Prague. The location of the apartment is perfect. It is right in the middle of the old town and you can walk easily to all sightseeing spots. Nevertheless it is quiet.
House + apartment are a bit older, but we felt comfortable.
We didn’t meet Alena in person, but it was very easy to get in contact with her and she managed everything perfectly (like the airport pick up).
I can recommend the apartment!
