It was a truly immersive experience staying with Maria, Carlos (her husband) and their 96 year old aunty. They have a lovely home/apartment in a lively Madrid neighbourhood. It was a shame that the metro wasn't operating while we were there, but this was explained in advance. Carlos spoke the most English and picked us up from the airport which we organised with Maria - definitely recommended if it's your first time in Madrid. Good wifi. Shops and supermarket close by. Really helpful with cooking and washing. Very pleasant hosts and we enjoyed our week in Madrid!
