I actually booked the other apartment by Kathrine and was moved to this apartment. Her lovely mother welcomed me and it was a great pleasure chatting with her in English. Since I was doing a Spanish class in Madrid, Katherine's mother encouraged me to speak also in Spanish with her. She is a very knowledgable person and gave me useful hints what to do and where to go in Madrid.
I stayed for one week and was assigned to the smallest room of the appartement. It has a window facing the patio of the building.
Altogether a very joyful experience to stay in the apartment.
