Jose Maria was very welcoming and helpful with any questions we had about getting around Madrid. He faced some problems with the television when we arrived and spent some time trying to fix it but it couldn't be done then, which was fine for us since we didn't need it anyway.
The accommodation was very artistic, modern and comfortable, pretty much set in a studio style. Well-furnished, kitchen had everything we needed, the toilet and shower room was spacious and clean. Great bed (and sofa bed!) and the air-conditioning in a hot summery Madrid was a huge plus. It's also on a touristy, famous street so it is very close to main attractions like Plaza Mayor, Puerta del Sol and the San Gines Chocolateria (great churros) and several metro stations
