The flat is totally okay for 2 people, maybe even 3, and it's located in a really cool neighbourhood where La Latina and Lavapiés are nearby. I came 6 hours late due to a flight delay but was still okay. The walls are very thin, so you gotta keep it quiet plus you may at some point recognize there are other people living in the building, but that was no problem for me. Overall, you may find a cheaper place but if you care about the area, this may be one of the best places you can find. Gracias por todos
