I would highly recommend Dolores as a host as well as her apartment to anyone coming to visit Madrid. Dolores is a particularly warm & welcoming host, who is always easy to reach. She gave a very thorough introduction to the apartment & made me feel at home.
The apartment itself is incredibly clean & tidy & in a great location. It feels more residential than the centre of the city but is still very central, with easy access to metro stations, supermarkets, restaurants, & shopping.
If I get the chance to visit Madrid again, I'll be checking to see if this apartment is free!
