My parents stayed in Madrid for three more days after our family stay in Latina Star 3. It was very convenient that they could just 'hop over' to Latina Star 2 in the same building, as Star3 was already booked.
This is how they experienced it:
"What a wonderful apartment! Clean, beautifully decorated with friendly colours. And the centre of Madrid within walking distance! Marta, thank you for this lovely place and for your kind hosting.
