Luis was very accommodating for our last minute booking, late night arrival and late check out. His son (I think) let us in but he popped by shortly after to make sure everything was all right. All we needed for 1 night and really close to a supermarket. The only thing you should know is that from the metro you have to go up quite a steep hill to get to the part of the city where the apartment is (10min walk or for about 3euros you can ride a team up). Other than that super close to the city center and a couple train lines. A bit noisy at night from a hotel bar across the street and early in the morning from a school across the road but with earplugs it wasn't an issue. Nice place, would stay there again.
