Wonderful place and hosts! We were so lucky to stay at Pilar's apartment!
It's on the other side of the river from Palacio Real, close to the metro and a very enjoyable walk to the center (40min, crossing the river, passing the Palacio Real, Calle Mayor).
The apartment is small, but very confy, clean, we were allowed to use all the appliances! Even the washing machine!
Pilar was away for holidays, so her partner welcomed us and even gave us a lift to the airport early in the morning !!!

I cannot say more, fantastic and welcoming hosts, very recommendable!
