She is a genuine person who is welcoming you with a warm heart and explaining what to see in Madrid better than any tourist guide.

I am happy to stay in her well-organised, certainly clean and cosy apartment which is located very close to metro-station and a lot of good places to eat. It is a best place for a single person or for a couple.

If I will visit Madrid again, there is no need to spend time for thinking where to stay. Answer is very obvious.
