The room is exactly as described on site. Right now you are also getting a small fridge and electric kettle inside your room. People living there (so Ignacio and Carmen as well as Carmen's parents) are lovely people, but they do only speak in Spanish, which can be a little bit problematic if you are not familiar with it. There is just one small thing that doesn't exactly match the description from AirBnB. I believe due to change mentioned above you are no longer allowed to use the kitchen.
Overall I believe this place is a great deal. It is close to city center and a great location to go out and sightsee in Seville. It is very near the Santa Justa train/bus station, so getting there is also quite easy. I would highly recommend it to anyone!
