The problem with giving glowing reviews is that when you want to book the apartment again, you can't because it's always booked! I didn't want to leave Alfredo and Ricardo's apartment. And I actually only did to have dinner but, otherwise, I stayed in the entire time. (I've been to Madrid before.)
Recommended for solo travelers or couples. Might be uncomfortable for three.
My only regret is not using their beautiful, well-equipped kitchen. Would have loved to whip up a meal there but I was too lazy.
When they put black-out curtains for the bedroom, the place will be perfect.
