Had the best stay at María Clara's place! Her flat is cosy, sparkling clean and located in one of the best barrios in Madrid - close to lots of restaurants/coffee shops/bars and walking distance to all of the main sites, but still quiet with a local feel. She made me feel at home and gave me recommendations of things to do, as well as places to eat. Initially I was worried about the fact that the flat didn't have heating, but there are portable heaters dotted around the flat that are used to keep it warm, so that was not a problem. The perfect place for a solo traveller - I will definitely be staying here again. Thank you María Clara!
