This apartment is a GREAT bargain and we LOVED the neighborhood. Lots of cafes, bars and shops right there. The local Mercado de la Cebada is only two blocks away with all kinds of fresh local fare. AND only a block away from El Rastro if you're there on a Sunday.
Ernesto's brother, Antonio, met us at the flat. We arrived earlier than expected, but he was already there waiting for us. He explained the door keys, thermostat and showed us the spotless apartment. We were delighted that the building has a lift as well, although the we were only one floor up. The wifi works very well - no connectivity issues.
A couple of things to know if you are not familiar with travel in Europe:
-Showers are smaller than you are use to
-They do not use washcloths, so bring your own if hand washing your body bothers you
-Power converters will be needed
-Buildings are old and the stairs may not be exactly even
The apartment is spacious and was PERFECT for our family vacation. I would definitely stay here again or encourage others to rent this flat if they have the opportunity to travel to Madrid.
