I had a great (though short) stay with Jorge. The process was smooth from the beginning, and it was very easy to communicate with him about check-in. You CANNOT beat the location, mere steps from the Atocha station. Also, the apartment is nice and stylish and very clean. Jorge will do everything to make you feel at home. He even welcomed me with 'tortilla de patata' (Spanish omelette). I highly recommend this place!
