I've been using some airbnb, and this place was the best.
The location was great, it was right next to everything.
In order to get inside to the building, you have to unlock many doors, which is great for security.
I slept on sofa bed, and the sofa bed was really comfortable, and there was comforters and sheets for sofa bed (usually people don't provide comforters to sofa bed).
When I had little problem to get into the door, I sent a message, and the daughter of Jose came to check us in 30 minute!
The floor was marble(? or tile), which is little cold to walk on barefoot, but it should be great for summer time.
I loved this place, with all free little bread with orange marmalade.
If I am going to visit Sevilla, I would definitely stay at this place
