Juan Miguel was an excellent host. He and his wife were very friendly and if we had any questions he was always available and responded to our messages on airbnb straight away.
The apartment was excellent, quiet, equipped with everything you'd need and in a good position for walking to all the sights in Old Seville.
The loft bed is very comfortable, but for those who are claustrophobic you may prefer the couch for sleeping (which was also very comfortable).
We would definitely recommend Juan Miguel's apartment for your Seville stay.
