Luis was fantastic, great host for our stay in Madrid, he welcomes us with a bottle of wine. Location wise, you can't ask for more, it is within walking distances to major tourist attractions and an easy 5 mins walk from Opera metro station. The neighborhood is safe at day & night to walk; if there is one negative side, it will be to walk 3 stairs up to the apartment, but the location and Luis's hospitality fully compensates this point, would highly recommend people to stay at Luis's apartment.
